Question
A rectangular tank is 60 meters long and 40 meters deep.
If 1800 cubic meters of water is drawn off the tank, the level of the water in the tank goes down by 3 meters. How many cubic meters of water can the tank hold? and find the breadth of the tank.ÂSolution
volume of the tank = (x ×h)/d = (1800×40)/3 = 24000m3   . And now the breadth of the tank = x / l d =1800/60×3 = 10m
