Question
A rectangular tank is 50 meter long and 29meter deep. If
1000 cubic meters of water be drawn off the tank, the level of the water in the tank goes down by 2 meters. How many cubic meters of water can the tank hold? and find the breadth of the tank.Solution
volume of the tank = (x ×h)/d = (1000×29)/2 = 14500m3                . And now breadth of the tank = x / l d =1000/50×2 = 10m
