Understanding Cubic Feet
Cubic feet (ft³) measures volume in three-dimensional space. To calculate cubic feet, multiply length × width × height (all in feet). 1 cubic foot = 1,728 cubic inches = 0.037 cubic yards = 28.317 liters.

Volume Calculation Formulas
Rectangular Prism: length × width × height. Cylinder: π × radius² × height. Triangular Prism: (base × height / 2) × length. All dimensions must be in the same units before calculation.

Volume Calculation Breakdown
Volume Calculation Formula
Volume (Cubic Feet) = Length (ft) × Width (ft) × Height (ft)
The volume is calculated by multiplying the three dimensions together. All units must be converted to feet first for accurate cubic feet calculation. For cylinders: Volume = π × radius² × height.
