What is measurements expressed in meters cubed?

The cubic meter can be simply thought of a cube, where all sides measure 1 meter across. It has a volume of 1000 liters.

The cubic meter is used in various ways, for example, the density of air is measured by stating the weight of air in a cubic meter. This is extensively used in thermodynamics for working out gas turbine engine efficiency.

large volumes are also generally measured in cubic meters.
