Question

Calculate the volume of the solid given below.

• A. 18 cu units
• B. 38 cu units
• C. 36 cu units
• D. 44 cu units

Answer 1

The correct option is B 38 cu units

We split the given solid into the following two cuboids:


Volume of the solid
= Volume of cuboid 1 +
volume of cuboid 2

Volume of a cuboid
= length $\times$ breadth $\times$ height

$\therefore$ Volume of cuboid 1 = 9 $\times$ 2 $\times$ 1
= 18 cu units

Volume of cuboid 2 = 2 $\times$ 2 $\times$ 5
= 20 cu units

$\therefore$ Volume of the solid
= 18 cu units + 20 cu units
= 38 cu units
