1) Volume measures how much space an object occupies, while mass measures the amount of matter. Volume is like size and mass is like weight. 2) Volume is measured in cubic units like cubic centimeters (cc) or cubic meters. One cc is the volume of a cube with 1 cm sides. 3) Liquid volume is also measured in cc or milliliters (mL), where 1 mL = 1 cc. Graduated cylinders are used to measure liquid volumes in the classroom.
