Mensuration prob #2

In a swimming pool measuring 90m by 40m, 150 men take a dip. If the average displacement of water by a man is 8 cubic metres, what will be the rise in water level?

Solution and explanation pls?

total volume displaced by men = 150 * 8 = 1200 m^3

so height = 1200/90*40 ==> 1/3 meter.
