Question

Calculate the height of the cuboid if its volume is 90 cu units.

• A. 9 units
• B. 10 units
• C. 3 units
• D. 5 units

Answer 1

The correct option is A 9 units

Volume of a cuboid
= length $\times$ breadth $\times$ height
= 5 $\times$ 2 $\times$ h
= 10h cu units

But, volume = 90 cu units.

$\therefore$ 10h = 90
$⟹$ h = $\frac{90}{10}=9\text{units}$

Hence, the height of the cuboid is 9 units.
