Capacity of cubical tank = 242 × 44 = 10648 m3 Let, side of cubical tank = ‘x’ m So, x3 = 10648 m3 x = 22 m So, height of cylindrical tank = 14 m Let, radius of cylindrical tank = ‘r’ m So, 2 × 22/7 × r × 14 = 1936 r = 22 m Volume of cylindrical tank = 22/7 × 22 × 22 × 14 = 13552 m3 Required difference = 13552 – 10648 = 2904 m³
