What is the derived unit of volume?

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas) or shape occupies or contains.

Mathematically, the volume is given as

V = $Area \ of \ base \times height$

Unit of area = metre square

Unit of height = metre

So derived unit of volume =$ m^2 \times m = m^3$

or cubic metre
