Step-by-step explanation:
The tank is in the shape of a cuboid.
Volume of a cuboid =l×b×h.
Since, after 5 hours, the height of the water is 20cm,
Volume of water in the tank in 5 hours =225×162×
100

=7290m

Let x m/ hour be the speed of the water flowing thought the aperture.
Then, Volume of water flown through the aperture in 5 hours =(

Now,
