Question

5 litres of a solution in $m^3$
is

• A. $5\times {10}^{-3}{m}^3$
• B. $5\times {10}^{-6}{m}^3$
• C. $5m^3$
• D. $5\times {10}^3{m}^3$

Answer 1

The correct option is A $5\times {10}^{-3}{m}^3$

We already know that
$1litre=1000{cm}^3$
$\therefore 1litre=1000\times ({10}^{-2}{)}^3{m}^3=1000\times {10}^{-6}{m}^3$
$\therefore 1litre$ = ${10}^{-3}{m}^3$
5 litre= ?
$\therefore$ $\frac{5\times {10}^{-3}}{1}$ = 5 $\times$ ${10}^{-3}$
$\therefore$ 5 litres = 5 $\times$ ${10}^{-3}$ $m^3$
