Volume of a regularly shaped solid (book, kleenex box ect) is measured by L X W X H. The units used are cm3 or m3.
To measure volume of an irregularly shaped solid (marble, coin etc…) Place water in a graduated cylinder, measure the volume, place the item in the graduated cylinder with water, measure the new amount, the amount displaced is the volume of the solid. Do not forget to subtract your old amount from your new amount. Units used are mL or L since 1 cm3 = 1 mL.
