The lenght , breadth, and hieght of a cuboidal tank are 150cm, 120 cm, and 110cm respectively. The tank has 129600cm^2 of water in it. 100 porous bricks each having dimensions 20 cm * 10cm *10cm are placed in the tank. Calculate the rise in the water level of the tank, if each brick absorbs 1/10 of its volume.

Vol. of each brick=2000
vol.rise=2000
vol absorb=200
net rise=1800
for 100 bricks=180000
150*120*h=180000
h=10cm rise
