# Finding volume by counting cubes

The volume of a shape measures the three dimensional (3D) amount of space it takes up. Volume is measured in cubes.

A cubic centimetre is the volume within a cube that has sides of length $${1~cm}$$, as shown above. It has a volume of $${1~cm}^3$$ ($$1~cm$$ cubed).

This cuboid contains $$12$$ cubes. Each cube has a volume of $${1~cm}^3$$. So the volume of this cuboid is $${12~cm}^3$$.

Question

Find the volume of the following cuboids:

a)

b)

a) $${8~cm}^3$$

b) There are two layers of nine cubes, so the volume is $${18~cm}^3$$.

Question

Find the volume of the following 3D shape.

${11~cm^3}$
