How would you calculate the density of a substance?

To calculate the density of a substance, you divide its mass by its volume. Density is defined as the amount of mass contained in a given volume, typically expressed in units such as grams per cubic centimeter (g/cm³) for solids and liquids, or grams per liter (g/L) for gases.

The formula can be represented as:

Density = Mass / Volume

This relationship shows how compact the mass is relative to the space it occupies. The other options provided do not correctly describe the calculation of density: multiplying length, width, and height calculates volume; multiplying mass by volume does not provide any meaningful physical property in this context; and adding mass and volume also does not result in a property that describes density. Therefore, the correct approach to determine density is indeed to divide mass by volume.
