Reference: AQA
The mass per unit volume of a material, calculated as density = mass ÷ volume, with units such as kg/m³ or g/cm³.
A quantity measured in kilograms per metre cubed, kg/m³, and represented by the Greek letter ρ.
Found using ρ = m ÷ V, with mass as the numerator and volume in m³, giving the unit kg/m³.
The mass per unit volume of a material, calculated by dividing mass by volume.
Mass per unit volume, written as ρ = m ÷ V and measured in kg/m³ or g/cm³.
Defined by the equation ρ = m / V, as mass m divided by volume V.
