Question

Convert 200 cubic centimetres into cubic metres.

• A. 0.02
• B. 0.002
• C. 0.0002
• D. 0.00002

Answer 1

The correct option is C 0.0002

100 cm = 1 m
$\Rightarrow$ 100 $\times$ 100 $\times$ 100 $c{m}^3$ = 1 $m^3$
$\Rightarrow$ 1 $c{m}^3$ = $\frac{1}{100\times 100\times 100}$
$\Rightarrow$ 200 $c{m}^3$ = $\frac{200}{100\times 100\times 100}$
Cancelling two zeroes from numerator and from the denominator we have $\frac{2}{100\times 100}$ = 0.0002 $m^3$
