Cubic feet measure volume — the amount of three-dimensional space something occupies. It is the standard unit for moving estimates, shipping quotes, concrete orders, mulch, and storage units.
The formula:
Length (ft) × Width (ft) × Height (ft) = Cubic feet
Example: A storage unit 10 ft long, 8 ft wide, and 9 ft tall holds 10 × 8 × 9 = 720 cubic feet.
Common conversions:
For irregular rooms (L-shaped spaces), split the area into rectangles, calculate each volume separately, and add them together. A cubic feet calculator handles the arithmetic instantly, including unit conversions.
