A solid metallic cube having total surface area $\displaystyle 24 \mathrm{~m}^2$ is uniformly heated. If its temperature is increased by $\displaystyle 10^{\circ} \mathrm{C}$, calculate the increase in volume of the cube. (Given $\displaystyle \alpha=5.0 \times 10^{-4}{ }^{\circ} \mathrm{C}^{-1}$ ) .
Official answer
(2)
$\displaystyle 1.2 \times 10^5 \mathrm{~cm}^3$
