How many cubic yards of topsoil would there be on 100 acres of land if you averaged a 2' depth of material.


Hi Ken,

There are 43,560 square feet in an acre so there are 4,356,000 square feet in 10 acres. At a depth of 2 feet this gives you a volume of topsoil of 8,712,000 cubic feet. There are 3 feet in a yard so there are 33 = 27 cubic feet in a cubic yard. Hence dividing 8,712,000 by 27 I get 322,666.67 cubic yards.
