How to use it
- Enter the area length and width.
- Enter the depth: 2-3 in for paths, 4-6 in for driveways (in layers).
- Pick the material; densities are typical values.
- Read cubic yards and tons. Suppliers sell by either.
How it works
Cubic yards = length × width × depth (in) ÷ 12 ÷ 27. Tons = yards × density. Densities vary with moisture and stone size, so confirm with your supplier.
