Square area is the side squared. A 12 ft side at 4 inches deep is 48.00 ft³ (1.78 yd³).
A circular bed is the mulch circle calculator.
One side is enough
Both edges are the same length. If the sides differ, use the rectangle mulch page.
Depth turns area into volume
A 12 ft side is 144 ft². Four inches is 4/12 of a foot, so the volume is 48.00 ft³.
Worked example: Square Mulch
Side 12 ft, depth 4 in. Area 144.00 ft², volume 48.00 ft³ and 1.78 yd³.
\[ V = 12^{2} \times 4/12 \]
