You already have a square yard of topsoil, so how does 20 inches of depth get you the volume of topsoil? There are 36 inches in a yard, and you have 20 inches of topsoil depth that's 20/36ths of a yard of topsoil depth. That's 0.555... or about 0.56 yards. The volume of topsoil is 1 yard by 1 yard by 0.56 yards, or about 0.56 cubic yards of topsoil.
It depends on what it consists of. It could vary greatly.
Slightly less than 26 cu. yards.
Almost exactly 2.00 cubic yards for every inch of topsoil depth.
For an area that is 20ft by 20ft and you want to add 6 inches of topsoil, you will need 20 cubic yards of topsoil. Topsoil is typically ordered by the cubic yard, so this measurement will ensure that you have enough to cover the entire area with a 6-inch layer.
Topsoil is NEVER sold by the "truck-load". Usually in yards or tons, as there are several differant sizes of trucks... A "yard" of dry topsoil should weigh a little less than 1 ton.
You would need 31.88 cubic yards of topsoil to cover 855 sq feet at 6 inches deep.
Insufficient information.You need to know the depth of topsoil you want to cover those 7550 sq ft.By "yards" I assume you mean cubic yards -- a volume measurement.
77/9 cubic yards for every inch of depth.
For a 60cm depth of topsoil, you would need 0.6 cubic meters (or approximately 0.78 cubic yards) of topsoil. This calculation is based on the formula: Volume = Area × Depth.
In the US, dirt is measured in cubic yards. The average full sized pick up truck can usually hold about 2 to 3 cubic yards of dirt or topsoil. It varies a bit depending on the size of the pick-up and how strong its springs are. If you are having it filled for the first time, take it slow and watch how much the truck drops as it is being loaded.
