π‘ 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.
