Question 3: A water pool is 6 meters wide, 20 meters long and 2 meters deep. If 1 liter is equal to 1 kilogram then to fill half of the pool will require waht quantity of water ?
a. 120000 kg b. 250000 kgs c. 240000 d. None of these

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 !
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
