How to use Volume Calculator

Select a 3D shape, enter its dimensions such as radius and height, and the volume is computed instantly with the formula shown.

Frequently asked questions

Which 3D shapes are supported?

Eight solids: cube, rectangular box, sphere, cylinder, cone, pyramid, prism and more, each with the correct volume formula.

How is the volume of a cylinder found?

Volume = π × r² × h, using the base radius and the height of the cylinder.

What units are used?

Any consistent unit — enter dimensions in the same unit and volume is returned in that unit cubed (e.g. cm³).
