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?

The volume of a rectangular tank can be calculated by multiplying its length, width, and height.
Volume of the tank = length * width * height
Given:
Length = 25cm
Width = 20cm
Height = 30cm
Volume of the tank = 25cm * 20cm * 30cm
Now, let's calculate this:
Volume of the tank = 15000 cubic cm
Since the tank is half-filled, we need to find the volume of water already present in the tank, which is half of the total volume of the tank.
Volume of water already present = 15000 cubic cm / 2
Now, let's calculate this:
Volume of water already present = 7500 cubic cm
To find out how many liters of water will raise the water level by 5cm, we need to find the volume of water that will fill a 5cm high portion of the tank.
Volume of water to raise the water level by 5cm = length * width * 5cm
Volume of water to raise the water level by 5cm = 25cm * 20cm * 5cm
Now, let's calculate this:
Volume of water to raise the water level by 5cm = 2500 cubic cm
To convert cubic cm to liters, we divide the volume by 1000.
Volume of water to raise the water level by 5cm = 2500 cubic cm / 1000
Now, let's calculate this:
Volume of water to raise the water level by 5cm = 2.5 liters
Therefore, to raise the water level in the glass tank by 5cm, we would need approximately 2.5 liters of water.
