Almost exactly 2.00 cubic yards for every inch of topsoil depth.
77/9 cubic yards for every inch of depth.
Slightly less than 26 cu. yards.
if that is 3 ft deep it would require 96 yards... IF it is 3 inches deep it would require 24 cubic yards

Almost exactly 2.00 cubic yards for every inch of topsoil depth.
You would need 31.88 cubic yards of topsoil to cover 855 sq feet at 6 inches deep.
77/9 cubic yards for every inch of depth.
Slightly less than 26 cu. yards.
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.
if that is 3 ft deep it would require 96 yards... IF it is 3 inches deep it would require 24 cubic yards
