Been looking online but am not apparently punching in the right keywords. What is the formula for finding the about of gravel I need for approximately a 20 feet by 20 feet square. (For extending my turnaround.)
Formula for amount of gravel I need

volume in cubic feet is the product of the lengths of sides in cubic feet. So, if you have a rectangular lot that is 20 by 20 by 0.5 foot (0.5 being the depth of gravel), your volume is 20*20*0.5 = 200 cubic feet of gravel. A cubic yard is 9 cubic feet, so, in this example, you would need 200/9 = 22.2 cubic yards of gravel.

A cubic yard is 27 cubic feet. 3*3*3 = 37
So 200/27 is 8 yards of gravel

If the stone yard/mill/mine sells by weight, you will need about 10-10.5 tons.
8 yards times 2600# per yard equals 20,800# or 10.5 tons. (based on the weight of crush and run limestone).You can also figure around 3400 pounds per yard so the 8 yards would be
27,000 pounds or 13-1/2 t>>volume in cubic feet is the product of the lengths of sides in cubicErrol: that is **27**
oops!

That's about 6,1m x 6,1m. Assuming you make it 0,15m high, you get about
5,6 cubic meters.BTW: Don't believe the other posters that do their math in feet and yard, these are _illegal_ units! :-P

About 10 1/2 ton IF using #2 crushed. More if using smaller
Formula??? I just punch it into my Project Calc Plus (10 bucks at Home Depot and came with a 12 foot tape measure as well)

Shhhh!!!!
I want to hear his lament about having 22 cubic yards of gravel in a huge pile at the end of his driveway. ]-)
Not as bad as the church men's club who got the idea of paving a couple of parking spots for the minister and organist with hot mixed asphalt - Fortunately the truck driver was a quick thinker who knew that there was a crew just finishing a driveway nearby. Gerry :-)} London, Canada
Six, "1m x 6", "1m". What's this list mean?
Imperial is still legal in USA. :-P~

Why dont you take a long walk off a short pier.
You got me trapped! :-[ We use "," as a decimal seperator. Read "6.1m x 6.1m" etc.
Metrical law enforcement troops are on their way ...
