Answer:
False
Explanation:
Mass and volume are two different quantities. In fact:
- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.
- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (
).
Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

where
m is the mass
V is the volume
So the density of a substance represents the amount of mass contained in a certain volume of the substance.
