How many cubic feet of dirt is needed to build a raised garden bed that is 4 feet wide by 12 feet long by 12 inches deep?

Answer 1

The formula for the volume is length * height * depth (or width) = 33 =3*3*3 = 27 cubic feet, but the answer to the question is 0; there's no dirt in a hole... We are not digging a hole here; we are building a mini-mastaba that is 1 foot deep above the original ground level. 48 cubic feet of dirt is required which equals 48/27 = 1.78 cubic yards of dirt.
