Question

Which of the following is equal to 4 cubic metres?

• A. 2000000 cubic centimetres.
• B. 5000000 cubic centimetres.
• C. 3000000 cubic centimetres.
• D. 4000000 cubic centimetres.

Answer 1

The correct option is D

4000000 cubic centimetres.

1 m = 100 cm

Take the power 3 on both sides. We get..

$(1m{)}^3=(100cm{)}^3$

$\Rightarrow 1^3{m}^3=(100{)}^{3}c{m}^3$

$\Rightarrow 1\times 1\times 1m^3=100\times 100\times 100c{m}^3$

$\Rightarrow 1m^3=1000000c{m}^3$

$\Rightarrow$ 1 cubic metre = 1000000 cubic centimetres.

Hence 4 cubic metres = 4000000 cubic centimetres.
