Final Question
How do you calculate density of irregular and regular objects? Regular shaped objects you find volume by L x W x H and divide mass by volume. Irregular shaped objects you find volume by filling a graduated cylinder partly with water and then dropping the object in. The difference in the water line is the volume of the object. Then you divide mass by volume.
