The length, breadth and height of a cuboidal tank are 150 cm, 120 cm and 110 cm respectively. The tank has 129600cm3 of water in it. 100 porous bricks each having dimensions 20cm×10cm×10 cm are placed in the tank. Calculate the rise in the water level of the tank, if each brick absorbs 110 of its own volume.

1.	The length, breadth and height of a cuboidal tank are 150 cm, 120 cm and 110 cm respectively. The tank has 129600cm3 of water in it. 100 porous bricks each having dimensions 20cm×10cm×10 cm are placed in the tank. Calculate the rise in the water level of the tank, if each brick absorbs 110 of its own volume.
Answer» The length, breadth and height of a cuboidal tank are 150 cm, 120 cm and 110 cm respectively. The tank has $129600 c m^{3}$ of water in it. 100 porous bricks each having dimensions $20 c m \times 10 c m \times 10$ cm are placed in the tank. Calculate the rise in the water level of the tank, if each brick absorbs $\frac{1}{10}$ of its own volume.
