Verified step by step guidance

1. Understand that the International System of Units (SI) defines base units for fundamental physical quantities such as length, mass, and volume.
2. Recall that the SI base unit for length is the meter (m), which measures distance.
3. Recognize that the SI base unit for mass is the kilogram (kg), which measures the amount of matter in an object.
4. Note that the cubic meter (m\^3) is a derived SI unit used to measure volume, not mass.
5. Understand that the liter (L) is a common unit for volume but is not an SI base unit; it is related to the cubic meter (1 L = 0.001 m\^3).
