Question

The following figure shows a solid of uniform cross-section. Find the volume of the solid. All measurements are in centimeters.

Assume that all angles in the figures are right angles.

Answer 1

The given figure can be divided into two cuboids of dimensions 6 cm, 4 cm, 3 cm, and 9 cm respectively. Hence, volume of solid 

= 9 x 4 x 3 + 6  x 4 x 3
= 108 + 72
= 180cm³
