Question:
Find the surface area of a wooden box whose shape is of a cube, and if the edge of the box is 12 cm.
Solution:
It is given that the side of the cubical wooden box is $12 \mathrm{~cm}$.
$\therefore$ Surface area of the cubical box $=6 \times(\text { side })^{2}=6 \times(12)^{2}=864 \mathrm{~cm}^{2}$
