VOLUME

• Volume Definition: The amount of space an object takes up.

• Tools/Instruments for volume: – Liquid volume: Graduated Cylinder – Solid volume: Ruler

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).

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.

• What is the volume of the liquid?

• Answer: 70 mL

• What is the volume of the liquid?

• Answer: 27 mL

What is the volume of the liquid?

• Answer: 54 mL

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
