Question

The capacity of cuboidal is 50000 liters of water. Find the breath of the tank, if its length and depth are respectively 2.5m and 10 m.

Answer 1

$1m^3=1000litre$

$\Rightarrow 1litre={10}^{-3}{m}^3$

$\Rightarrow 50000litre={10}^{-3}\times 50000m^3$

$=50m^3$

$Volume=length\times breath\times depth$

$\Rightarrow 50=2.5\times breath\times 10$

$\Rightarrow breath=\frac{50}{25}=2m$

Correct answer is 2m
