assuming no loss of oil due to spillage?

Solution:

Density (D) = $\frac{\text{mass}}{\text{volume}}$

$\therefore \text{Mass} = \text{Density} \times \text{volume}$

= $0.4 \times 20 = 8\,\text{kg}$

The initial volume = $\frac{\text{Mass}}{\text{Initial density}}$

= $\frac{8}{0.8} = 10\,\text{m}^{3}$
