Question

a swimming pool is 24m long and 15m broad. when few men dive into the pool, the height of the water rises by 1cm. if the average amount of water displaced by one man is 0.1m cube, how many men are there in the pool?

Answer 1

Length=24m
Breadth=15m
Height=1cm=0.01m
Volume=l×b×h
=24×15×0.01=3.6m^3
0.1m^3 water is displaced = 1 man
3.6m^3 water is displaced=3.6/0.1=36men
So,36 men are there in the pool.
