Frequently Asked Questions
How do you calculate cubic feet?
Cubic feet = Length (ft) × Width (ft) × Height (ft). If your measurements are in inches, divide each by 12 first (or divide the result by 1,728). For example: a box 24" × 18" × 12" = 2ft × 1.5ft × 1ft = 3 cubic feet. Cubic feet is commonly used for shipping, storage units, refrigerators, and concrete calculations.
How many cubic feet in a cubic yard?
There are exactly 27 cubic feet in one cubic yard (3ft × 3ft × 3ft = 27 ft³). This is important for ordering concrete, fill dirt, mulch, or gravel — these materials are typically sold by the cubic yard. Divide your cubic feet total by 27 to get cubic yards needed.
