Here's the formula:
Density = Mass / Volume
Units:
* Density: Often expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
* Mass: Typically measured in grams (g) or kilograms (kg).
* Volume: Usually measured in cubic centimeters (cm³) or cubic meters (m³).
Understanding Density:
Density tells us how tightly packed the matter is in a substance. A high density means a lot of mass is crammed into a small space, while a low density means the mass is spread out more.
Example:
* Lead is a very dense material. This means that a small piece of lead has a lot of mass.
* Air is a very low-density material. This means that a large volume of air has very little mass.
