    Question

    A pipe fills a cubical tank at the rate of 128

    m3 per minute in 32 minutes. If a cylindrical tank having height same as the side of a cubical tank and the curved surface area of the cylindrical tank is 1408 m2, then find the difference between the volumes of cylindrical tank and cubical tank.
    A 5256 m³ Correct Answer Incorrect Answer
    B 8520 m³ Correct Answer Incorrect Answer
    C 2904 m³ Correct Answer Incorrect Answer
    D 960 m³ Correct Answer Incorrect Answer
    E 5760 m³ Correct Answer Incorrect Answer

    Solution

    Capacity of cubical tank = 128 × 32 = 4096 m3 Let, side of cubical tank = ‘x’ m So, x3 = 4096 m3 x = 16 m So, height of cylindrical tank = 16 m Let, radius of cylindrical tank = ‘r’ m So, 2 × 22/7 × r × 16 = 1408 r = 14 m Volume of cylindrical tank = 22/7 × 14 × 14 × 16 = 9856 m3 Required difference = 9856 – 4096 = 5760 m³
