Question

A swimming pool of length 10 m and height 6 $\frac{1}{2}$ m can contain 5,20,000 litres of water. What is the breadth of the swimming pool?

• A. 4 m
• B. 8 m
• C. 6 m
• D. 9 m

Answer 1

The correct option is B

8 m

Volume = 5,20,000 litres

1000 litres = 1 cubic metre

$5,20,000litres=\frac{520000}{1000}=520cubicmetres$

Given:

length= 10 m

height = 6 $\frac{1}{2}$ =$\frac{13}{2}$ m

Volume $V=length\times breadth\times height$

Volume $520=10\times breadth\times \frac{13}{2}$

$\Rightarrow 520=10\times breadth\times \frac{13}{2}$

$\Rightarrow 520=65\times breadth$

$\Rightarrow breadth=\frac{520}{65}=8m$
