Density is defined as the mass of an object divided by its volume. Mathematically, it is expressed as:
\[
\text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)}
\]
where:
- \(\rho\) (rho) is the density,
- \(m\) is the mass of the object, and
- \(V\) is the volume it occupies.
Density is typically expressed in units such as kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). It is a physical property that can help identify substances and determine how they will behave in different environments, such as whether they will float or sink in a fluid.
