I need to know how much stone I will need to cover an area that is 30 feet long by 20 feet wide. Also the gravel will be 5 inches deep.?

30 x20x .415 / 27 = 9.22 cubic yards

Brake down for inches to 10ths divide 10 by 12 this will convert into 10ths times your inches thickness desired. (Apx.)

1" = .083
.083x5 = .415
lenght x Width x Thichness
20 x 30 x .415
