The equation for the density of an object is given by:
\[ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} \]
where:
- \(\rho\) is the density,
- \(m\) is the mass of the object,
- \(V\) is the volume of the object.
Density is typically expressed in units such as kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
