5. Explore: You can find the volume of an object using just a graduated cylinder if you don't have access to an overflow cup. This technique works if the object you are measuring is
small enough to fit into the graduated cylinder.

Return the overflow cup and the 25-ml graduated cylinder to the cabinet. Take out the
100-ml graduated cylinder and the pipette. Fill the 100-ml graduated cylinder to exactly
40.0 mL, using the beaker and the pipette.

A. Drag the rock into the 100-ml graduated cylinder. Use the magnifier to read
the new volume. What is the current water volume in the graduated cylinder?

B. How much has the water volume changed in the graduated cylinder?

C. Based on your answers to A and B, what is the volume of the rock?
