Density Formula

ρ = Mass / Volume

Units: g/cm³ or kg/m³ (1 g/cm³ = 1000 kg/m³)

SubstanceDensity (g/cm³)
Iron7.87
Copper8.96
Aluminium2.70
Wood (oak)0.60
Water1.00

Method

  • For Regular SolidsMeasure mass on a balance. Calculate volume from dimensions (L × W × H for cuboid).
  • For Irregular SolidsMeasure mass. Use water displacement in a measuring cylinder to find volume.
  • Key ConceptObjects with density < 1 g/cm³ float in water. Objects with density > 1 g/cm³ sink.
