Here's why:
* Liters measure the amount of space a substance occupies (volume).
* Centimeters measure the length of something (distance).
To compare these units, you need to consider the shape of the container:
* A cubic centimeter (cm³) is a unit of volume.
* 1 liter (L) is equal to 1000 cubic centimeters (cm³)
Example:
If you have a cube that is 10 cm on each side, it has a volume of 10 cm x 10 cm x 10 cm = 1000 cm³, which is equal to 1 liter.
