A rectangular glass tank is half filled with water. The measurements of the tank are 30cm in height, 25cm in length and 20cm in width. How many litres of water will raise the water level in the glass tank by 5cm?

  1. each 1cm layer of water has a volume of 25x20x1 = 500 cm^3

    so, it doesn't matter how much water is in the tank -- a 5cm rise in height contains 2500 cm^3 of water.

    So, how many litres is that?

  2. 2500 cubic centimetres = 2.5 liters.
