This page starts from a known area. 250 ft² covered 2 inches deep is 41.67 ft³ (1.54 yd³). It does not draw a shape, because the area is already a number.
A rectangular bed is the mulch rectangle calculator.
Area is already known
Measure the bed first, then enter that area and a depth in inches.
Depth turns area into volume
Two inches on 250 ft² is 250 × 2/12 cubic feet. That is the settled depth, not a bag count.
Worked example: Mulch Volume
Area 250 ft², depth 2 in. Volume 41.67 ft³ and 1.54 yd³.
\[ V = 250 \times 2/12 \]
