VOLUME • Volume Definition: The amount of space an object takes up. • Tools/Instruments for volume: • Liquid volume: Graduated Cylinder • Solid volume: Ruler
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). Units
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.
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.
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)
What is the volume of the solid? 10 cm 2 cm 10 cm
Answer: 10 X 2 X 10= 200 cm3 10 cm 2 cm 10 cm
What is the volume of the solid? 6 cm 2 cm 11 cm
Answer: 11 X 2 X 6= 132 cm3 6 cm 2 cm 11 cm
What is the volume of the solid? 15 cm 3 cm 5 cm
Answer: 5 X 3 X 15= 225 cm3 15 cm 3 cm 5 cm
