• It would be nice to share some informatin about the calculation of volume of some common geometrical shapes such as cylinder, sphere etc. Also information about how to convert between different volume units such as cm3 to dm3, m3 to mm3 would be nice. We always have to use such as a tool like http://www.onlineconversion.com/volume.htm or http://www.easyunitconverter.com/volume-unit-conversion/volume-unit-converter.aspx without understanding ourselves how we can convert volume units by hand.

### Cycles of Matter : How do we measure volume?

1. 1. How do we measure volume? A Science Lesson By Christine Tan 19 Jan 2009
2. 2. What is Volume? <ul><li>The volume of an object is the amount of </li></ul><ul><li>space it takes up . </li></ul>Question : What is the difference between mass and volume?
3. 3. Units of Volume <ul><li>We measure volume in 3 ways : </li></ul><ul><li>Cubic centimetres </li></ul><ul><li>Mililitres </li></ul><ul><li>Litres </li></ul>Questions : How do we write them? What are the differences between each of them?
4. 4. Measuring Volume <ul><li>We can measure volume of objects with irregular shape in two ways : </li></ul><ul><li>The volume of the water that flows out </li></ul><ul><li>The difference between the volume of water and the total volume of the water and the object. </li></ul>Question : Does the volume of an object change when its shape changes?
