I came up with 12 also bobby.Originally posted by bobbygedd
i'm commin up with 18 yds. 40x18.5=740 sq ft. one yd of soil covers 100 sq ft 2 " deep. so to cover this area at 2" deep would be 7.4 yds. but, i need 5 " so, i multiply the formula by 2.5, this equals 18.5 yds of topsoil. i cant screw it up, it's all wheelbarrowing and shoveling, through a tiny gate. i've always used the formula of 1 yd of soil, covers 100 sq ft, 2" deep. it's never failed me. am i wrong?
