A pool is 59.8 m long and 26.6 m wide. If the average depth of water is 3.70 ft, what is the mass (in kg) of water in the pool?

klio [65]

Given :

Length , l = 59.8 m.

Breadth , b = 26.6 m.

Depth , d = 3.7 ft .

Density of water , $\rho=1\ g/ml=1000\ kg/m^3$ .

To Find :

Mass of water in pool .

Solution :

First we will covert depth into m from ft .

$1\ ft =0.3\ m$

For ,

$3.7\ ft=0.3\times 3.7\ m\\3.7\ ft=1.11\ m$

So , volume of pool is :

$V=59.8\times 26.6\times 1.11\ m^3\\\\V=1765.65\ m^3$

We know , density is given by :

$\rho=\dfrac{m}{V}$

So , $m=\rho V$

Putting given values in above equation :

$m=1000\times 1765.65\ kg\\\\m=1.77\times 10^6\ kg$

Hence , this is the required solution.
