Greetings,
This post features a simple derived unit, commonly known as space or size: Chemists call it volume. The volume unit is derived from a metric fraction of the SI base unit of length, the meter. A 1/100 fraction of a meter is a centimeter. A perfect cube with 1 cm dimensions occupies a 1 cubic centimeter volume.
The cubic centimeter volume is used for solids. One cubic centimeter is the same volume as one milliliter (1 mL), a unit used by chemists to measure the volume of a liquid. If we now imagine a larger cube that is 10 cm long on each side, we now have a cube which occupies a volume of 1000 cubic centimeters. A 1000 cubic centimeter volume can be expressed as 1000 mL, also known as 1 liter (1 L).
The following diagram summarizes this volume discussion.

Remember this: Where there is volume, there is also mass, and then we know we have matter!
What kind of ratios can be written for volume? From the diagram, we can write 1 mL/1 cm e3. This can also be thought of as a conversion factor.
That's all for this post. Thanks for reading!
