A rectangular water tank of length 60 cm and width 40 cm contains water up to depth of 30 cm. A peice of ice measuring 20 cm by 15 cm by 12 cm is dropped into the tank of water. Calculate the new depth of water when the ice melts completely, assuming its volume decreases by 1/10.

the ice's volume is 20*15*12 = 3600 cm^3
melted, the volume is 3600-360 = 3240 cm^3
The area of the water is 2400 cm^3
That means the water level will rise by 3240/2400 = 1.35 cm
