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.
    A 13.62 Correct Answer Incorrect Answer
    B 16.67 Correct Answer Incorrect Answer
    C 12.24 Correct Answer Incorrect Answer
    D 14.25 Correct Answer Incorrect Answer

    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
