How is the density of solids calculated?

The density of solids is calculated using the formula that defines density as the mass of the substance divided by the volume it occupies. In this case, when dealing with solids specifically, the formula applied is the mass of the solids divided by the volume of the solids. This relationship illustrates that density is a measure of how much mass is contained in a given volume, which is critical when assessing material properties such as strength, stability, and overall performance in engineering applications. The unit of density is typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³), making this calculation essential for various material testing procedures. The other options do not correctly represent the definition of density for solids. One involves the mass of voids, which is not relevant when calculating the density of actual solid materials. Another option inaccurately suggests using the total mass versus just solids, which dilutes the purpose of finding out the density of only the solid portion. Thus, the most accurate expression sits with the correct formula, which captures the true essence of density for solids.
