Question

If 210 cubic metres of sand be thrown into a tank 12 metre long and 5 metre wide, find how much the water will rise?

Answer 1

length = 12 m
breadth = 5m
volume = 210m^3
length × breadth × height = volume
12 * 5 * height = 210
height = 210/60
height = 3.5 m
therefore the height upto which the water will rise = 3.5 m
