The symbol most often used for density is ρ (the lower case Greek letter rho ), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [1] where ρ is the density, m is the mass, and V is the volume. old suwanee christian school gaWebFeb 17, 2024 · Mathematically, density is expressed as mass divided by volume. This means that the more mass an object or substance has in a given volume, the more dense it is. An object's density depends on the mass, size, and arrangement of its atoms. Other factors that affect density are air pressure and temperature. old swahiliWebAug 11, 2024 · The density of copper is 8.96 g/cm 3.
