Density - Wikipedia

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.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: = where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the ...
