How many cubic yards in an acre 20 yards deep?

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.

How much topsoil will i need to cover 880 square feet?

That depends on the depth of the topsoil you will put down. Multiply the number of square feet by the depth of topsoil--that will give you the number of cubic feet. To convert to cubic yards, divide the number by 27. So, for example, if you are using 3" of topsoil over 880 square feet then your calculation would be: 880 times .25 (3" = .25 feet) = 220 cubic feet (divided by 27--there are 27 cubic feet in a yard) equals 8.15 cubic yards.
