Density of any substance within an area is calculated by the volume of an infinitely small volume in that area and divided by this infinitly small volume.

The density unit can be measured in kilograms per cubic meters (kg/m3) (according an international system for measurement). There are also units in grams of cubic centimeter (g/cm3).

The density of objects to identify the materials in the objects by comparing the results of substances previously determined with the table of density.

Formula for calculating density:

D = m/V

Then It is D, which represents the density (kg/cm3) and m is the weight of the item (kg) while V represents the quantity (m3).
