Answer :
A fish tank with a capacity of 100 litres is filled with 20000 ml of water.
To find:
how much more water is needed to fill it up completely?
Solution:
The capacity of a fish tank is 100 litres
converting litres to ml:
1 litre = 1000 ml
100 litres = 100 x 1000 ml
100 litres = 100000 ml
It is given that the fish tank is filled up with 20000 ml of water.
we need to find how much more water is needed to fill it up completely:
=> 100000 ml - 20000 ml
=> 80000 ml
Hence, 80000 ml of more water is needed to fill it up completely.
Final answer:
To fill a 100 litre fish tank that already contains 20 litres of water (20000 millilitres), one would require an additional 80 litres of water (or 80000 millilitres).
Explanation:
The question is asking how much more water is needed to fill a fish tank with a capacity of 100 litres that currently has 20000 millilitres (which equals to 20 litres) of water in it.
First, we need to understand that 1 litre is equivalent to 1000 millilitres. This means that the fish tank, with a total capacity of 100 litres, can hold up to 100,000 millilitres of water.
The fish tank already has 20,000 millilitres of water (and remembering that 20000 millilitres is equal to 20 litres). Therefore, the volume of water still needed to fill the tank can be found by subtracting the volume of the water currently in the tank from the tank's total capacity: 100,000 millilitres - 20,000 millilitres = 80,000 millilitres. Transformed back into litres, this will make 80 litres of water that is still needed to fill the tank.
