What is Cubic Feet?
Cubic feet (ft³) is a unit of volume used to measure three-dimensional space. It represents the volume of a cube with sides that are 1 foot long.
For example:
- A box measuring 1 ft × 1 ft × 1 ft = 1 cubic foot
- A larger container measuring 5 ft × 3 ft × 2 ft = 30 cubic feet
This measurement is widely used in construction, logistics, interior design, and even appliance capacity calculations.

Formulas Used in the Calculator
Understanding the formulas can help you verify results:
- Box (Rectangular Prism):
Volume = Length × Width × Height - Cylinder:
Volume = π × Radius² × Height - Sphere:
Volume = (4/3) × π × Radius³ - Cone:
Volume = (1/3) × π × Radius² × Height
Example Calculations
Example 1: Box
A storage box measures:
- Length = 6 ft
- Width = 4 ft
- Height = 3 ft
Volume = 6 × 4 × 3 = 72 cubic feet
Example 2: Cylinder
A water tank has:
- Radius = 2 ft
- Height = 5 ft
Volume = π × 2² × 5 = 62.83 cubic feet (approx.)
Example 3: Sphere
A ball with:
- Radius = 3 ft
Volume = (4/3) × π × 27 = 113.10 cubic feet (approx.)
Example 4: Cone
A cone-shaped container:
- Radius = 2 ft
- Height = 6 ft
Volume = (1/3) × π × 4 × 6 = 25.13 cubic feet (approx.)
