Student PagesDensity of SolidsIntroductionIn this activity, two cubes and a bar that have the same physical appearance will be used to introduce the concepts of volume, mass, and density. Concepts
BackgroundIn this activity, the mass, volume and density of two cubes and a bar will be determined and compared by measurement. The volume of any regular solid can be calculated using Equation 1. The length, width, and height must be determined using a metric ruler. {11964_Background_Equation_1}
Once the solid object’s mass and volume are known, the density may be found using the following equation. {11964_Background_Equation_2}
Density, which is defined as an object’s mass divided by its volume, is a characteristic property of a material. Solids that have the same physical appearance or objects of different shapes and sizes may be identified by their densities. The density of a solid is commonly expressed as g/cm^{3}. Materials
