How is density calculated?

Density is defined as the mass of an object divided by its volume. This relationship can be expressed mathematically by the formula:

Density = Mass / Volume

This calculation provides a measure of how much mass is contained in a given volume, which is an important property in various scientific fields, including physics, chemistry, and engineering. Understanding density is crucial for determining whether an object will float or sink in a fluid, as well as for various applications in material science, buoyancy studies, and many industrial processes.

The other options provided do not accurately reflect the definition or formula related to density. For example, mass plus volume or mass minus volume does not yield a meaningful measurement of density. Therefore, the correct answer, which highlights the proper calculation of density, is simply mass divided by volume.
