Question

Find the volume of the given shape.

• A. 20000$m{m}^3$
• B. 24000$m{m}^3$
• C. 48000$m{m}^3$
• D. 10000$m{m}^3$

Answer 1

The correct option is A

20000$m{m}^3$

The shape can be visualised as a cuboid of dimensions $80mm\times 50mm\times 10mm$ from which a smaller cuboid of dimensions $50mm\times 40mm\times 10mm$ is cut out.

So, volume of the resulting shape is $(80mm\times 50mm\times 10mm)–(50mm\times 40mm\times 10mm)=40000–20000=20000m{m}^3$
