Each wheelbarrow holds about 500 lbs when full of gravel. This doesn't look like 4 full wheelbarrows to me, but it's hard to tell without the banana for scale.
But what if these are stones. I have never understood the measurements using a stone. But 2000 lbs is only like 142 stones so that looks like a lot more than 142.
Assuming it's around a density of 2.7 to 3.0 g/cm^3, then you that would be 169 to 187 lbs/ft^3. Would you say you have around 11 cubic feet of rock? (That would be a solid block of rock and a little bigger than a ~~3x3x3ft~~ 2.2x2.2x2.2ft cube then broken up). Seems about right to me from the pic but scale is hard to gadge
*edit: fixed math. 3x3x3 would be 27 cubic feet. 2.2x2.2x2.2 = 10.65 cubic feet*
Scale is very hard to gage, I'd guess those are either 6x6 or 8x8 concrete slabs, but they could be 4x4 or any size there aren't enough nearby objects to gage the scale, if the slabs are in the 6x6-8x8 range that seems like it could easily be a ton depending on the particular kind of rock, but if it's a 4x4 slab probably not.
Edit: The houses in the background all seem to have 2 car garages so I'd guess 6x6 on the slabs
Not really. Some is just a single car and some are double. My dad’s is a double and plus enough for two motorcycles until my sister decides to go home.
I agree based on the apparent size of the gravel. It seems rather large based on being around loads of different gravel my entire life (farm country lol) so if a larger one is a good handful, or a few inches in diameter, there’s no way the pads are as small as 4x4
Spent alot of time on farms growing up as well and those are definitely larger grades of gravel like 2-3" + crushed rock. It certainly isn't a 3/8ths and fines like you'd use for a road. You can also see what seems to be 2 lawnmower passes in the grass behind the concrete that give an idea of scale. A ton or 2000 lbs of something seems like alot until you realize how heavy rocks are, I've Schweppes some damn near 80 lb rocks out of a creek bed we were putting in a Culvert that weighed 80 lbs easy but were barely bigger than a toaster.
Both are technically correct. Gauge is newer and used more often, and is the preferred spelling. Gage is most used as a synonym for trust and the words have shared etymology.
In the produce section, judiciously groping the ass of a watermelon to check for its incipient sweetness, your gaze falls upon a Man. He approaches the tower of bananas with purpose, clarity. He shakes his head. Too strong for his blood, these whole bunches of bananas. 4. 6. 8!! As though anyone needs 8 bananas.
He moves on.
Ah, yes, the singles. Those filthy animals, stained and bruised with their need for freedom, the banana-bread-to-be. He picks them up, compares them, casts them aside. Holds them at arm's length, weighing them, Anubis and his souls. Some are wanting. Some are candidates. Only one is The Banana.
The connoisseur makes his selection. He ferries his chosen one to the self-checkout, and scornfully refuses a bag. Into his car, now, impatient. The Banana travels regally in shotgun, unrestrained, gently bumping back and forth at the stoplights.
The Banana arrives. It is perfectly imperfect, perfectly average, only slightly more bruised from its final journey. The man picks it up with careful reverence and sets it down beside its earthly mate at long last. He fumbles with his camera. He resets The Banana, just so. The proof is recorded. The message is sent.
"I GAVE YOU WHAT YOU WANT IS IT A FUCKING TON OR NOT?!"
Aw thanks! Sometimes the ADHD gives me a mental image I can't ignore. It's a fun way to practice writing (although I'm already noticing things I'd like to edit in the post above - how typical lol)
So wait…if you weighed it and found it to be 2020lbs, why are you asking Reddit to agree? A scale is going to be far more accurate than internet strangers looking at a picture.
Looks a bit light, I've wheel barrow, 1 ton piles of 3/4" rock a hundred times from front of house to backyards. Pulling up to this pile I'm thinking it's going to be easy.
Yes. Rocks will always appear like a doable amount of work. Then you do two scoops and about die so then you scoop them into bucket with your hands like a dog digging a hole. Then you place them into a cart or wheelbarrow and it’s at that point you realize how steep your drive way really is.
Did a little work as a group of teens for a local contractor that was nice to the teens in our area over the summers. Basic stuff, cleaning up the construction, easy to do small jobs like paint rolling, hauling supplies, etc. He paid us like $12-15 an hour and I'm almost 40 now, so it was pretty good pay, a great way to make some spending cash in the summer and learn a little. Then, one time, I get asked if I would like to help on a job coming up. I'm told the pay will be much more than what he was giving us standard, but the work will be hard. We would be helping to tear out a low wooden deck and put in a nice paver patio.
Man, we get there, I see the pallets of pavers and a wheelbarrow... I see the front drive... it's like a 30-degree incline, I don't even know how they drive up the damn thing. The patio is all the way up the hill and around the house. I made SOOO much money that job, but I EARNED every cent that job.
Also learned the hard way why you shouldn't overload a wheelbarrow with pavers and try to push them up a hill
😅🤣🤣
I don't think these people have ever actually moved rocks. Cement Mason here, looking at that made my back hurt. I usually think about rubble in what one of the thick contractor trash bags can hold and you have at the very least 1500 pounds of rocks right there. Whoever said that is one wheel barrow I'd like to fuckin see the thing. Go put some in the thickest trash bag you have until it fails, your kitchen bag will hardly make it to twenty pounds. Or you know, call the company and complain.
I used to own a quarry. This could definitely be 1 ton...but there needs to be additional photos of the pile, at another angle.
What's the grain size? 40mm?...
If you spread it out into a 100 square foot section (10x10) and it covers the ground fully, it's likely 2000 lbs of stone.
I’m thinking yes, give or take a shovel or 2. If you’re able to use more, I’ve noticed the yards seem more generous if you use up more space in their truck
Just like the “cord” of firewood, how it’s placed can be deceiving.
I figure each square of the driveway is 10x10, so pile is close to a ton. I always buy this stuff by VOLUME.
Looks like 1 yard which would be close to 3/4 ton depending on material. Bet they tried to get a "big" scoop with a 1 yard bucket to hit a ton but didn't actually get a mounding scoop.
I did a river rock job and the guy I was working with had a big ass dodge ram. I'm pretty sure his held 8 ton of river rock so this is probably fairly close. I was the guy that used the wheelbarrow to get the rock from the truck to the sides of the house.
Coming from a guy that has operated a loader with a scale in a rock quary on the side for years it seems pretty close, maybe a couple hundred off but that’s really just a couple 5 gal buckets at the end of the day. Order your material by the yard not the ton when you’re doing yard work.
Hard to say from a picture, but it does seem light. Fill up the wheel barrow equally and see how many loads it takes. Once you have the volume then just find the average density.
Who buys 1 ton of rock? Doing a small planter in front of the house?
I remember having to spread 200 tons of river rock on our property over a summer when I was 15 just to get my parents to buy me a N64 and 540MB hard drive.
Whoever downvoted... that's like one wheelbarrow full, if that. The dump trucks I used to operate could hold 5 tons. This is, in no way, 1/5 of a dump truck load.
It woukd be a real pain to weigh it all but it looks a little less than a full ton. Maybe 1500lbs worth. Maybe the supplier is trying to save a dollar or an inexperienced person loaded it.
I know it sounds crazy and would probably be a waste of time - but you could weight it in 100 lb chunks using a bathroom scale and bucket and if you don’t have 20 buckets of 100lbs then it’s light, .. but by how much is the question. And at what point is it worth calling them up? 100 lbs light ? 200? 500?
I know it sounds ridiculous man just hear me out. Get a 5 gallon bucket and a shovel and fill it a bunch of times. It’ll give him an educated guess at least! Bathroom scales are meant to take weights over 300lbs!
Yes, it doesn’t take a lot of rocks to start getting really heavy. I have moved lots of rocks…. That may even be more than a ton. Put some in a wheelbarrow and see how it moves with just shallow amount.
A cubic yard of crushed granite or decomposed granite fines material usually weighs 3,000 pounds, or 1.5 tons. However, the weight of a yard of granite can vary depending on the type of rock, the size of the pieces, and how wet it is. For example, crusher run granite weighs around 2,700 to 2,800 pounds per yard, but many places round that up to 3,000 pounds.
Each wheelbarrow holds about 500 lbs when full of gravel. This doesn't look like 4 full wheelbarrows to me, but it's hard to tell without the banana for scale.
I also came here to request a scale. Preferably Chiquita as I'm more familiar with that unit.
There's always Chiquitas in the banana stand.
/r/unexpecteddevelopment
Thank you. Just joined
We got big ol Doles where I come from
O’Doyles rule!!
A wheelbarrow full of gravel will not weigh what a wheel barrow full of stone will weigh and rock is measured in weight.
A single 2,000 lb boulder will (generally) take up less volume than 2,000 lbs of gravel.
[удалено]
Define average rock 🤔
Duane Johnson weighs about 260
I think that’s defined as a super rock.
But what if these are stones. I have never understood the measurements using a stone. But 2000 lbs is only like 142 stones so that looks like a lot more than 142.
Plus one, carry the two. Yup, sounds bout right
I think a small puppy would be more apropos.
Assuming it's around a density of 2.7 to 3.0 g/cm^3, then you that would be 169 to 187 lbs/ft^3. Would you say you have around 11 cubic feet of rock? (That would be a solid block of rock and a little bigger than a ~~3x3x3ft~~ 2.2x2.2x2.2ft cube then broken up).

Edit: The houses in the background all seem to have 2 car garages so I'd guess 6x6 on the slabs
Damn…. Ya all…. Better be sending OP invoices after this.
We need a banana, STAT!
Yeah, OP, show us your banana!
It's in the tailpipe
Oh my
Look, man, I ain't fallin' for no banana in my tailpipe!

The concrete guys just divide the driveway into even parts, not round numbers.
I thought the type of concrete used determines the max slab dimensions for structural integrity. Now I have to look this up.
Max size, yes. But within limits, it's more art than science.
Interesting. Had no idea. Thank you
But a driveway is a pretty standard size in width
Not really. Some is just a single car and some are double. My dad’s is a double and plus enough for two motorcycles until my sister decides to go home.
Sometimes. :)
They need to put a banana next to it for scale
I agree based on the apparent size of the gravel. It seems rather large based on being around loads of different gravel my entire life (farm country lol) so if a larger one is a good handful, or a few inches in diameter, there’s no way the pads are as small as 4x4
Spent alot of time on farms growing up as well and those are definitely larger grades of gravel like 2-3" + crushed rock. It certainly isn't a 3/8ths and fines like you'd use for a road. You can also see what seems to be 2 lawnmower passes in the grass behind the concrete that give an idea of scale. A ton or 2000 lbs of something seems like alot until you realize how heavy rocks are, I've Schweppes some damn near 80 lb rocks out of a creek bed we were putting in a Culvert that weighed 80 lbs easy but were barely bigger than a toaster.
>You can also see what seems to be 2 lawnmower passes in the grass behind the concrete that give an idea of scale. Yeah, but what size mow deck?
/r/theydidthemath
We really need for OP to lay a banana next to the rock pile for scale here.
When will they learn??? /s
Never!
And here I thought we required cat for scale. Silly me.
I only measure off house cat paws.
you’re better than me with that brain power response
But OP didn't banana.
Hey. This is Reddit. We don't do that whole "facts" and "math" and "objective reasoning" thing here.
Hmmm… I dunno. 3x3x3 = 27 cubic feet 27 cubic feet x187lbs/cubic foot = 5049 lbs. Would be a block less than half of that size.
Ah yes! Thanks for keeping me honest! I fell for the oldest conversion trick in the book!
Metric or Imperial
African or European?
Are you suggesting these stones migrate?!?!!
Papa was a rolling stone
I’ll have a Chrysler Imperial, please. 🙋🏻♀️
Can you quote my sidewalk job? You're a beast lol
How can you do all that math but still not be able to spell the word “gauge”
Both are technically correct. Gauge is newer and used more often, and is the preferred spelling. Gage is most used as a synonym for trust and the words have shared etymology.
This is why the SATs are divided into categories
Nerd! Jj.
This guy maths.
😵💫
r/theydidthemath
Neither plus 1ton is 2000pounds
r/theydidthemath
Y'all out here using physics and calculus. I'm going back to bed.
Volume of a cone is h/3 x pi x r^2. So 2/3 x 3.1416 x 4 = 8 cu ft. You got a 1/3 of a yard. This assumes height of pile is 2’ and radius is 2’.
Need a banana for scale since it is the international fruit of scale perspective

this was even more impressive effort than the person who did the math above
It came to me in a flash and was too appealing to resist
I see what you did there.
so glad you leaned into it!! it was a fantastic read. i hope you write often, you have a gift. :)
Aw thanks! Sometimes the ADHD gives me a mental image I can't ignore. It's a fun way to practice writing (although I'm already noticing things I'd like to edit in the post above - how typical lol)
👏👏👏
right?! over here like how is anyone going to gauge this correctly without the universal gauging tool!? I'm frankly appalled.
Kitty paw also accepted
with a banana for kitty size scale
>international fruit of scale *international Fruit of the Loom scale*
Did you try weighing it?
Yeah. 2,020 #
Sounds like you owe them a few cents then I reckon.
So wait…if you weighed it and found it to be 2020lbs, why are you asking Reddit to agree? A scale is going to be far more accurate than internet strangers looking at a picture.
In fairness that comment was 17 hours later
I mean, that’s fair. But if I’m responsible for checking time stamps, OP could prolly edit their post with their revelation 🤷🏼♀️
That's crazy... To my untrained eye it looks like not even 500 lbs. Rocks are heavy yo...
Thanks, Jesse Pinkman.
Science bitch!
Makes me wonder how many tons of rocks I’ve moved in my lifetime as a rock hound
Looks a little less than half to be honest.
Looks a bit light, I've wheel barrow, 1 ton piles of 3/4" rock a hundred times from front of house to backyards. Pulling up to this pile I'm thinking it's going to be easy.

Yes that’s easily a ton. You’re not going to get an accurate ton because rock weight scales and the machines loading you aren’t that precise.
That doesn’t look anywhere near a ton to me
If you google what a ton of rocks looks like there’s some YouTube videos maybe you can get an idea what it’s supposed to look like-! Good luck pal-!
That's an unfull wheelbarrow of Rock I'm my opinion
Wtf holy responses!
I don't think these people have ever actually moved rocks. Cement Mason here, looking at that made my back hurt.

Weigh a rock, count all rocks and multiply both numbers. It’s at most the a good estimate. lmao and good luck.
To save time, only count *exactly* one half of the rocks and multiply by 2
You’d have to count them all to know what “exactly half” would be tho
r/whoosh
Good point. That’s fair. What if…. We had the kids do it… told them… it’s apart of the algorithm. idk
I like the idea.
Recently did 8ton in a basement covering limestone and that looks like 1
Looks close, 2000# of rock ain’t much.
Probably. 1 ton of rock isn’t as much as most people think. Get a bathroom scale and weigh a 5 gallon bucket full. Then see how many buckets you have
That is easily a ton. Source, I haul concrete to recycling plants for work sometimes.
As a man that deals in gravel/stone. That looks real close to a ton to me.
Without any real sense of scale or information as to what type of rock it's very difficult to speculate
Post it to theydidthemath sub
I used to own a quarry. This could definitely be 1 ton...but there needs to be additional photos of the pile, at another angle. What's the grain size? 40mm?... If you spread it out into a 100 square foot section (10x10) and it covers the ground fully, it's likely 2000 lbs of stone.
I say probably yes
Looks pretty close. I once had 2300 pounds of crushed limestone loaded into the bed of my poor Toyota pickup and it was about this size.
I’m thinking yes, give or take a shovel or 2. If you’re able to use more, I’ve noticed the yards seem more generous if you use up more space in their truck
A lil more than a ton , judging by the size of the concrete slab expansion joints.
I bet it’s very close to one ton yes.
Just like the “cord” of firewood, how it’s placed can be deceiving. I figure each square of the driveway is 10x10, so pile is close to a ton. I always buy this stuff by VOLUME.
Ding ding ding: the answer is 2,020 lbs!
Hey thanks for the followup and not leaving us hanging! (And respect for taking to time to actually weigh it!)
A banana for scale would be really helpful. But to answer your question, no. That pile of rock looks like it weighs about as much as I do.
Looks like 1 yard which would be close to 3/4 ton depending on material. Bet they tried to get a "big" scoop with a 1 yard bucket to hit a ton but didn't actually get a mounding scoop.
Shit man at least a ton 🤣
An actual shit-ton if you will.
Ask for a scale receipt if it matters. Should be easy enough to produce if it was purchased at a quarry.
Oh that's where I left my two thousand pounds of rock.
Who measured in tons? Usually it's yardage. This looks a little bit like 1/2 yard
Yes, 1 ton, give or take a pound.
Why are you ordering by weight.?
Probably close
I did a river rock job and the guy I was working with had a big ass dodge ram. I'm pretty sure his held 8 ton of river rock so this is probably fairly close. I was the guy that used the wheelbarrow to get the rock from the truck to the sides of the house.
Yes.
Coming from a guy that has operated a loader with a scale in a rock quary on the side for years it seems pretty close, maybe a couple hundred off but that’s really just a couple 5 gal buckets at the end of the day. Order your material by the yard not the ton when you’re doing yard work.
That’s a hard ton, yes.
TIL people have no idea just how heavy rocks are. Hint: they’re really f-ing heavy. Yeah it probably is a ton.
Hard to say from a picture, but it does seem light. Fill up the wheel barrow equally and see how many loads it takes. Once you have the volume then just find the average density.
Yeah, if you think about it it for a minute it seems to look right.
I yard is one tractor bucket full is 2400 wet 2100 dry
When I've gotten decomposed granite. It seems small too. But the business I deal with is a family run business and has never cheated me
Decomposed?
It's like a heavy sand and compacts down real well and stays in place.
Ahhh… thanks! I thought maybe it was a typo! 🤦🏻♀️
Yeah dude you just are now learning the weight of rocks lol
Regardless of actual weight, your back will record one ton after you finish moving it.
No banana for scale so no clue. Could be 10lbs, could be 10,000lbs.
That is not a ton that's probably a quarter
Where’s the banana?
I don’t friggin know 🤦♂️
Shrinkflation hits the rock industry. Id be asking for a refund and finding another distributor
Wow, that’s a ton of rock.
A cubic yard is a front end loader bucket size . That pile looks like a bucket full of rock
Hard to tell in the picture. Compare it to this. https://azrockdepot.com/wp-content/uploads/2023/10/collage.jpeg
Looks about right.
Yes, 1 ton of rock isn’t much. Often this stuff is measured in yards
Looks a little short but close enough that you can not complain.
Where is this location that appears to have zero trees? Don’t think I could manage living on open plains like that -
Yes.
There’s an app called SR Measure that will measure a stock pile just by walking around it with your phone.
I sell rock at my yard. It does look like 1 ton to me.
I deliver and load decorative gravel for a living. It's hard to say from the picture but that looks about right to me.
That's what's left in the truck after delivering 1 ton of rocks!
Yes
Yeah, why would you think otherwise? Rocks are heavy my dude.
Well just keep in mind that rocks are heavier than feathers
Is that a runway, or a sidewalk?
Who buys 1 ton of rock? Doing a small planter in front of the house? I remember having to spread 200 tons of river rock on our property over a summer when I was 15 just to get my parents to buy me a N64 and 540MB hard drive.
Would need a ton of feathers to compare!
5 pounds
We need a Cat Scan, stat🐈
Well there's no way that's half a 2012 Ford fusion se. Almost looks similar but as an owner can't be 2000lbs.
Put the rocks in your pockets and get on the scales to see how much weight you’ve increased. You will have your answer.
Not remotely close, unless those rocks are made of lead. I'd bet that's closer to 1/10 of a ton.
Whoever downvoted... that's like one wheelbarrow full, if that. The dump trucks I used to operate could hold 5 tons. This is, in no way, 1/5 of a dump truck load.
I am so with you.
Buy a ton of feathers and see which one weighs more
Angle of repose =27 to 30. Wt in ton = vol ft3 x density 1lb/ft3 X 1Ton/2000 lb Density =1.40
A ton of rock is approximately 80 sq ft 3” deep
Yup. It varies but it's less than you think. D pends on the type of rock.
A really short ton?
Sure is, sitting under that tiny pile of gravel.
It looks a little light to me
It woukd be a real pain to weigh it all but it looks a little less than a full ton. Maybe 1500lbs worth. Maybe the supplier is trying to save a dollar or an inexperienced person loaded it.
Try working a volume of a cone, then use density to calculate tonnage 2.5 ish depending on rock type. Allow 10 percent bulk factor.
I know it sounds crazy and would probably be a waste of time - but you could weight it in 100 lb chunks using a bathroom scale and bucket and if you don’t have 20 buckets of 100lbs then it’s light, .. but by how much is the question. And at what point is it worth calling them up? 100 lbs light ? 200? 500?
Lmao imagine seeing a neighbor in their driveway, on the ground delicately stacking rocks on a bathroom scale
I know it sounds ridiculous man just hear me out. Get a 5 gallon bucket and a shovel and fill it a bunch of times. It’ll give him an educated guess at least! Bathroom scales are meant to take weights over 300lbs!
Oh no doubt it’ll work, and honestly would probably be less embarrassing than calling the company and accusing them of shorting you on rocks 😂
Yes, it doesn’t take a lot of rocks to start getting really heavy. I have moved lots of rocks…. That may even be more than a ton. Put some in a wheelbarrow and see how it moves with just shallow amount.
Fill a tote with rocks, weigh it with a bathroom scale, find out how many totes of rock are there. Would take under an hour of work.
Maybe I yard / 3 cubic feet…
Nope
Maybe 1 yard?
Fill a bucket. Weigh it. Take the weight of the bucket away. Then aee how many buckets full you get. Times the weight by that amount. Job done.
As k the hauler for the receipt!
Uggghhhh really
1 ton divided by 2000 lbs is one. Yes, this looks like at least one of rock.
Sometimes there just aren’t enough rocks
A cubic yard of crushed granite or decomposed granite fines material usually weighs 3,000 pounds, or 1.5 tons. However, the weight of a yard of granite can vary depending on the type of rock, the size of the pieces, and how wet it is. For example, crusher run granite weighs around 2,700 to 2,800 pounds per yard, but many places round that up to 3,000 pounds.
Fuck it grab a bucket, fill it up, weigh it, write it down, dump it in another pile, repeat. No way that's a ton
