Question

Find the height of a cuboid of volume 100 cm³, whose length and breadth are 5 cm and 4 cm respectively.

Answer 1

\[\text { Let us suppose that the height of the cuboid is h cm . } \]

\[\text { Given }: \]

\[\text { Volume of the cuboid = 100 } {cm}^3 \]

\[\text { Length = 5 cm }\]

\[\text { Breadth = 4 cm }\]

\[\text { Now, volume of the cuboid = length } \times \text { breadth } \times \text { height }\]

\[ \Rightarrow 100 = 5 \times 4 \times h\]

\[ \Rightarrow 100 = 20 \times h\]

\[ \therefore h = \frac{100}{20} = 5 cm\]
