Hi, i'm another gardener that has forgotten how to calculate "how much topsoil in cubic yards i need to order to cover 7500sq. ft. 3 inches deep"?
thanks Maggie
Hi Maggie,
A yard is three feet so a square that is one yard by one yard is 3 feet by three feet, and hence 3 
3 = 9 square feet.
Thus 7500 square feet is 7500/9 = 833.33 square yards.
Three inches is 12/3 = 0.25 feet and hence 0.25/3 = 0.08333 yards. Thus you need
833.33
0.0833 = 69.4 cubic yards.
