Solution
\[\text { Let us suppose that the height of the cuboid is h cm . } \]
\[\text { Given }: \]
\[\text { Volume of the cuboid = 100 } {cm}^3 \]
\[\text { Length = 5 cm }\]
\[\text { Breadth = 4 cm }\]
\[\text { Now, volume of the cuboid = length } \times \text { breadth } \times \text { height }\]
\[ \Rightarrow 100 = 5 \times 4 \times h\]
\[ \Rightarrow 100 = 20 \times h\]
\[ \therefore h = \frac{100}{20} = 5 cm\]
