Question

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

• A. 5 $\times$ ${10}^{-3}$ $m^3$
• B. 5 $\times$ ${10}^{-6}$ $m^3$
• C. 5 $m^3$
• D. 5 $\times$ ${10}^{-4}$ $m^3$

Answer 1

The correct option is A

5 $\times$ ${10}^{-3}$ $m^3$

We already know that
1 litre = 1000 c$m^3$
$\therefore$ 1 litre = 1000 × (10^-2)³ $m^3$
= 1000 × 10^-6 m³
$\therefore$ 1 litre = 10^-3 $m^3$ 5 litre= ? $\therefore$ $\frac{5\times {10}^{-3}}{1}$ = 5 $\times$ ${10}^{-3}$

$\therefore$ 5 litres = 5 $\times$ ${10}^{-3}$ $m^3$
