Question:
The volume of a room is 378 m3 and the area of its floor is 84 m2. Find the height of the room.
Solution:
Volume $=$ height $\times$ area
Given:
Volume $=378 \mathrm{~m}^{3}$
Area $=84 \mathrm{~m}^{2}$
$\therefore$ Height $=\frac{\text { volume }}{\text { area }}=\frac{378}{84}=4.5 \mathrm{~m}$
