Question

A rectangular tank can hold 650 litres of milk. If it is 130 cm long and 250 cm wide, then the height of the tank is

• A. 20 cm
• B. 25 cm
• C. 35 cm

Answer 1

The correct option is A 20 cm

Volume of rectangular tank
$=650litres=650\times 1000c{m}^3=650000c{m}^3$

We know,
volume of a cuboid $=l\times b\times h$
$\Rightarrow 650000=130\times 250\times h$
$\Rightarrow h=\frac{\left(650000\right)}{130\times 250}=\frac{\left(6500\right)}{13\times 25}=20cm$

Therefore, the height of the tank is 20 cm.
