How to calculate density

Density is calculated by dividing the mass of an object by its volume. The formula for calculating density is:

Density = Mass / Volume

1. Measure the mass of the object using a scale, in units such as grams or kilograms.
2. Measure the volume of the object using a ruler or other measuring tools, in units such as cubic centimeters or cubic meters.
3. Plug the mass and volume measurements into the density formula.
4. Divide the mass by the volume to determine the density of the object. The resulting unit of density will depend on the units used for mass and volume (e.g. g/cm³, kg/m³, etc.).

Example:
Let's say you have a block of wood with a mass of 500 grams and a volume of 200 cm³.

Density = 500g / 200cm³
Density = 2.5 g/cm³

So, the density of the block of wood is 2.5 grams per cubic centimeter.
