The formula for density is derived from the relationship between mass and volume. Density is defined as the mass of an object divided by its volume. This relationship allows us to understand how much mass is contained in a given volume of a substance, which is crucial in various scientific fields including physics, chemistry, and engineering.

When we express this relationship mathematically, we write density as mass divided by volume. This means that if you know the mass of an object and its volume, you can calculate its density by simply performing the division. This concept is fundamental in physical science because density helps in identifying substances and understanding buoyancy and material properties.

In contrast, adding mass and volume would not provide a meaningful measure in this context, nor would multiplying the two since mass and volume are different physical quantities. The other options do not accurately reflect the relationship established in the definition of density.
