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
