Question

A tank is in the shape of a cuboid of length 60 cm and width 50 cm. What should be its height to hold 4.5 litres of water? [Volume = capacity]

• A. 1.3 $cm$
• B. 1.6 $cm$
• C. 1.8 $cm$
• D. 1.5 $cm$

Answer 1

The correct option is D 1.5 $cm$

Given,
volume = 4.5 litres = 4500 $c{m}^3$.
($\because 1litre=1000c{m}^3$)
We know that,
volume of cuboid $=L\times B\times H$.
As volume is given as 4500 $c{m}^3$,
​​​​$4500=L\times B\times H$
$4500=60\times 50\times H$
H = $\frac{4500}{50\times 60}$
H = 1.5 $cm$
