* Cubic centimeter refers to a volume, the amount of space occupied by a three-dimensional object.
* Square is a two-dimensional shape.
Think of it this way:
* A square with sides of 1 centimeter long has an area of 1 square centimeter.
* A cube with sides of 1 centimeter long has a volume of 1 cubic centimeter.
Imagine a tiny sugar cube. That's about the size of 1 cubic centimeter.
