Question

If the volume of a cuboid is 729 m${}^3$ and the area of the base is 162 m${}^2$, then find the height of the cuboid.

• A. 7.5 m
• B. 6.5 m
• C. 4.5 m
• D. 5.5 m

Answer 1

The correct option is C 4.5 m

Volume of the cuboid = 729 m${}^3$
Area of the base (l × b) = 162 m${}^2$
$\because$ Volume of cuboid = l x b x h
Therefore, height of the cuboid $=\frac{\text{Volume of the cuboid}}{\text{Area of the base}}$
$=\frac{729}{162}$
= 4.5 m
