Principle
The density of a substance corresponds to the mass of a cubic centimetre of this substance. The density is thus defined as mass : volume (g/cm3). The density of irregular objects can be established by determining the mass by weighing it and the volume by the displacement of water. The density of the solids lead, iron, copper, brass, zinc, aluminium, hard rubber and wood are determined.
