# The Capacity of a Certain Cuboidal Tank is 50000 Litres of Water. Find the Breadth of the Tank, If Its Height and Length Are 10 M and 2.5 M Respectively. - Mathematics

The capacity of a certain cuboidal tank is 50000 litres of water. Find the breadth of the tank, if its height and length are 10 m and 2.5 m respectively.

#### Solution

$\text{ Capacity of the cuboidal tank = } 50000 L$

$1000 L = 1 m^3$

$i . e . , 50000 L = 50 \times 1000 litres = 50 m^3$

$\therefore \text { The volume of the tank is 50 }m^3 .$

$\text { Also, it is given that the length of the tank is } 10 m .$

$\text { Height = 2 . 5 m }$

$\text { Suppose that the breadth of the tank is b m }.$

$\text { Now, volume of the cuboid = length } \times \text { breadth } \times \text { height }$

$\Rightarrow 50 = 10 \times b \times 2 . 5$

$\Rightarrow 50 = 25 \times b$

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

$\therefore \text { The breadth of the tank is 2 m } .$
