Here's the formula:

Density (ρ) = Mass (m) / Volume (V)

* Density (ρ) is usually measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

* Mass (m) is typically measured in kilograms (kg) or grams (g).

* Volume (V) is usually measured in cubic meters (m³) or cubic centimeters (cm³).

Example:

Let's say you have a block of wood with a mass of 10 kg and a volume of 0.05 m³. To find its density, you would:

1. Divide the mass by the volume: 10 kg / 0.05 m³ = 200 kg/m³

Therefore, the density of the block of wood is 200 kg/m³.
