Question
A rectangular reservoir is 60 meters long and 40 meters
deep. If 1500 cubic meters of water is drawn off, the water level in the reservoir drops by 1.5 meters. Calculate the breadth of the reservoir and the total capacity of the reservoir in cubic meters.Solution
volume of the tank = (x ×h)/d = (1500×40)/1.5 = 40000m3                                                     . And now the breadth of the tank = x / l× d =1500/60×1.5 = 16.67m
