The amount of three-dimensional space an object occupies, measured in cubic units.

Frequently asked questions

Halve the diameter for the radius, then use πr²h ÷ 3. A 6-unit diameter and height 10 give about 94.25.

A cone holds one third of the cylinder with the same base and height.

It is half the diameter, so a diameter of 6 has a radius of 3.

Cubic units matching the diameter and height you enter.
