3. Units MAIN unit for liquid volume: LITER MAIN unit for a solid volume: cubic centimeters ( cm³ ) Most of the time in class we will be labeling in milliliters (mL).

4. VOLUME OF LIQUIDS For liquid volume we will use the instrument called a graduated cylinder To find the volume of liquids we look at the bottom curve of the water level in the graduated cylinder. The bottom curve of water is called a meniscus.

5. When reading the meniscus you use the bottom of the curve. You must be at eye level and have the graduated cylinder on a flat level surface.

12. Volume of Solids To find the volume of a solid we will use a ruler. We will measure the length, width, and height of the object. You will then multiply the three numbers Formula for volume-- Length x Width x Height Label in cm³ (cubic centimeters)

13. 10 cm 2 cm 10 cm What is the volume of the solid?
