- Enter the desired depth in inches.
- Select the material type from the dropdown.

The Formula
Volume (cu yd) = (Length × Width × Depth÷12) ÷ 27
Tons = Volume × Material Density
Tons = Volume × Material Density
Densities used: Gravel = 1.4 t/cy, Sand = 1.35 t/cy, Crushed Stone = 1.5 t/cy, Topsoil = 1.1 t/cy. Actual density may vary — confirm with your supplier.
