You can
put this solution on YOUR website! What does one thousand centimeters cubed of water fills a --------?
You say "centimeters cubed" but a more appropriate way to say it is
"cubic centimeters". But it does indeed mean "centimeters cubed"
The fact you must know here is that 1 ml = 1 cm³
That is to say, there is no difference between 1 milliliter and
1 cubic centimeter.
We know that 1000 milliliters makes 1 liter.
Since a milliliter is a cubic centimeter,
we then know that 1000 cubic centimeters makes 1 liter.
