Cube Volume Calculator

Everything about a cube from a single side.

Why volume scales with the cube

Double a cube's side length and its volume increases 8-fold (2³), not 2-fold — a reminder that scaling a 3D object up quickly multiplies the material or capacity needed far more than intuition suggests.

Practical uses

Shipping boxes, storage bins, aquariums, and ice cubes are all cube or near-cube shapes — this formula sizes their capacity and the material needed to build them.
