**Solution: **

Here we have been given that 1 Kg = 1 Litter, that is 1kg is equal to 1 liter volume!

To fill the pool half we will require water in liters equal in volume to half half volume of the swimming pool!

Let us calculate volume;

*Length of swimming pool =20m*

*Width of swimming pool = 6m*

*Depth of swimming pool = 2m*

Apply formula of volume;

So, volume of swimming pool is 240 meters cube. *Now we should know that one meter cube is equal to 1000 liters !*

So,

240000 liters of water can be filled in the whole swimming pool, Hence half filled swimming pool will contain half of volume;

But litter is equal to Kg

So, We need water 120000 Kgs
