Find the volume of the object through water displacement if the volume of the water was originally 10.6mL and after adding the object the volume of the water rose to 17.8mL.
V = 17.8mL - 10.6mL = 7.2mL?

In a similar lab to what you did, a student found the mass of an object to be 20.45g. His original water volume was 13.5mL and the volume of the water after adding the object was 17.5mL. Calculate the density.
What is volume of object = 17.5mL - 13.5mL = 4.0mL
d = 20.45g/4.0mL = 5.1 g/mL?
