Question

A residential housing society is built in 4000 sq metre area It has
an underground tank to collect the rain water, the length, breadth
and height of which are 50 m,40 m,4 m respectively If it rains at
the rate of 2mm per minute for 5 hours, then calculate the depth of
water in the tank

Height of rain water in 5hrs=2×5×601000m=0
6 mArea of housing society=4000 m2Volume of rain water=(4000×0
6)m3=2400 m3
Now,Depth of water in tank=Volume of rain waterArea of base of underground tankDepth of water in tank=240050×40=1
