The method use to determine the volume of the granite is more commonly called water-displacement method. A more common method that is usually used for irregularly shaped objects. To determine the volume of the granite, we just have to subtract the initial volume from the final volume. That is,
                     volume of granite = 40.7 mL - 32.6 mL = 8.1 mL
