**
Density = mass / volume
**

To find the density of a regular shaped object you must:

- calculate the volume of the object by using length X width X height in centimeters

- calculate the density using D = m/V

To find the density of an irregular shaped object you must:
- calculate the volume using water displacement

- calculate the density using D = m/V
