Question

On a rainy day, the water fall of a tank increased by 2 CM. The volume of water in the tank is increased by

Answer 1

Let the dimensions of water level in tank before rain fall be l, b, h

Volume of water at the present situation = lbh

After rain, height is increased by 2 cm.

The present dimensions of water level are l, b, h+2 .

so the volume of water = lb(h+2) = lbh+2lb.

Therefore, The volume is increased by twice it's product of length and breadth
