How do you find the volume of an irregularly shaped object?
Water Displacement Method
1. Fill the graduated cylinder with water.
2. Record the volume of the water.
3. Place your object into the graduated cylinder
4. Record the new water level.
5. Subtract the original water level from the new water level. Remember to show your work!
Example
