What is the height of a brick with a base area of 25 cm² and a volume of 225 cm³?

Given,

The volume of bricks = 225 cm³.

The base area is 25 cm².

The brick is in the form of a cuboid.

The volume of the cuboid = Base area x height

Hence the height of the cuboid = $\frac{\mathrm{Volume} \mathrm{of} \mathrm{the} \mathrm{cuboid} }{\mathrm{Base} \mathrm{area}}$ = $\frac{225 {\mathrm{cm}}^3}{25 {\mathrm{cm}}^2}$= 9 cm

Therefore, the height of the cuboid is 9 cm.
