πŸ’‘ Square Feet to Cubic Feet

Cubic feet = square feet Γ— depth (in feet). If depth is in inches, divide by 12 first. This conversion is essential for calculating how much material you need to cover an area at a given depth.

Common applications: concrete slabs, gravel base layers, topsoil, mulch, and sand. For example, a 200 sq ft patio with 4" of gravel base needs 200 Γ— (4/12) = 66.7 cubic feet.

200 sq ft Γ— 4 inches deep: 200 Γ— 0.333 = 66.7 cubic feet = 2.47 cubic yards.
