Choose the correct option: 

Find the height of a cuboid whose base area is 180 cm² and volume is 900 cm³.

Given, the base area of the cuboid = 180 cm²

volume of the cuboid = 900 cm³

we know that the volume of the cuboid = base area x height

height of a cuboid = $\frac{\mathrm{volume} \mathrm{of} \mathrm{the} \mathrm{cuboid}}{\mathrm{base} \mathrm{area}}$

Therefore, the height of a cuboid = $\frac{900 {\mathrm{cm}}^3}{180 {\mathrm{cm}}^2}=5 \mathrm{cm}$
