A 12 by 3 by 12 inches deep will require about 1.33 cubic yards of top soil. A cubic foot of top soil weighs in around 75-100 pounds. A 40 pound bag of top soil is about 2 or 2 1/2 cubic feet. It would fill an area one foot wide, two feet long, and one foot high. Rather than purchase bags of top soil, it would be more economical to have two cubic yards of topsoil delivered to your home. Why not check around for the best price?
