# Volume

- The amount of space an object takes up.

There are a number of derived units of volume in the British system of units and the SI system of units. Archimedes developed ways of measuring the volumes of solids in 220BC.

The cubic metre (m^{3}) is the SI unit of volume, equal to 10^{6} cm^{3} or 1000 litres.
