How it works
A cube packs s layers of s×s unit cubes, hence s cubed total unit cubes.
Formula
V = s³
How to use Volume of a Cube Calculator
- Enter the edge length.
- Read volume in cubic units.
- Compare with rectangular prism when only one dimension differs.
Worked examples
Concrete numbers and cases you can check against the tool above.
Shipping cube s = 18 in
V = 18³ = 5832 in³ — check carrier dimensional weight rules separately.
When to use Volume of a Cube Calculator
Cubes simplify storage math: one dimension fixes all three. Useful for dice, boxes, and unit-cell geometry.
Common use cases
- Volume of a cubic freezer compartment.
- Material in a cubic block given edge measure.
- Intro solid geometry drills.
Inputs and outputs
- Single edge length

Frequently asked questions
- Cube vs square?
- Square is area s²; cube is volume s³.
- Surface area included?
- This tool gives volume only; surface area is 6s² separately.
- Rectangular box?
- Use the rectangular prism volume tool when three edges differ.
