Q43

0. A tank is in the form of a cuboid. It holds a maximum of 540 m3 water. If the tank is 8 m long and 15 m wide, then how many metres deep must the water be when the tank is 2/3 full?

  • Option : D
  • Explanation : Volume of a cuboid (tank)=lxbxh
    ⇒ 540 m3 = 8 x 15 x h
    ⇒ Height of the tank = 540/8x15
                                            = 4.5 m
    Now, water height in the tank = 2/3 of tank height = 2/3 x 4.5 = 3 m
