Find the height of a cuboid of volume 100 cm

Let us suppose that the height of the cuboid is $h \mathrm{~cm}$.

Given :

Volume of the cuboid $=100 \mathrm{~cm}^{3}$

Length $=5 \mathrm{~cm}$

Breadth $=4 \mathrm{~cm}$

Now, volume of the cuboid $=$ length $\times$ breadth $\times$ height

$\Rightarrow 100=5 \times 4 \times h$

$\Rightarrow 100=20 \times h$

$\therefore h=\frac{100}{20}=5 \mathrm{~cm}$
