How much soil for raised bed?

Calculate: length × width × depth (all in feet) = cubic feet. 4×8×1 ft bed = 32 cu ft. Soil bags are 1.5-2 cu ft each, so 32÷1.5 = 21 bags. I built 4×8×1.5 ft bed—calculated 32 cu ft, bought 20 bags (1.5 cu ft each) = 30 cu ft (ran out 2 cu ft short). Learned to add 10% extra.
