Question

A swimming pool is 200M long and 120M wide. 36 litre of water is pumped into it . Find the rise in level of water?

Answer 1

area of top lxb 200×120= 24000
litres 36=0.036 m cube
24000× h=0.036
h=0.036÷24000
h=1.5e-6

Answer 2

The rise in level of water is 0.0000015  m

Step-by-step explanation:

$1000 liters = 1 m^3$

$1 liter = \frac{1}{1000}m^3$

$36 liters = \frac{1}{1000} \times 36 =0.036 m^3$

Length of pool = 200 m

Breadth of pool = 120 m

Volume of pool =$Length \times Breadth \times Height = 200 \times 120 \times Height$

36 litre of water is pumped into it .

So, $200 \times 120 \times Height = 0.036$

Height = $\frac{0.036}{200 \times 120}$

Height = 0.0000015  m

Hence  the rise in level of water is 0.0000015  m
