2.   Volume is defined as the amount of space taken up by a three-dimensional object. What is Volume

3.   We use Length x Width x Height for regular shaped solids.  EX: 6 X 6 X 6  EX: 12 x 5 x 6 How do we calculate it?

4.  How to Measure LENGTH Review

5.   Most metric rulers have lines indicating centimeters and millimeters.  The centimeter lines are the longer, numbered lines.  The shorter lines are millimeter lines.  When you use a metric ruler, line up the 0-centimeter mark with the end of the object being measured.

9.  Back to volume..

10. However, Volume often refers to liquid volume, which is defined as the amount of space taken up by a liquid, which spreads completely to fill its container.

11.  Measuring Liquid Volume  We will use the graduated cylinder.  The reading must be done to the bottom of the meniscus.

12. Volume of Liquids Reading a Meniscus

13.  Look to the scale

14. 

16.  What if its not a regular shape?  We then have to measure by displacement

17.  Measuring Volume by Displacement  Used for irregular shaped objects  Select a graduated cylinder large enough to put the object in  Add water - at least 10 mL and record accurately

18.   SLOWLY add the object to be measured.  Read the new level of the water  The water will rise an amount equal to the volume of the object

19.  What not to do

20.  Here’s what the cylinder should look like

21.  1. Original reading of volume 2. Final volume of water 3.This will equal the volume of the object  22.5 mL - 17.4 mL = 5.1 mL  Therefore, the volume of the object by displacement is 5.1 mL Do the math
