Dimensional Analysis part 1

In this video we will take a look at dimensional analysis.
Questions:
1. Without using numbers, what are some fractions we can use that equal 1?
2. How would converting volume, from cm^3 to L^3, be different that converting area, from cm^2 to m^2?
3. Give an example of a time when you would need to change the units in the numerator and the denominator in order to complete a conversion.
4. Convert 3 well-known measurements (for example a 10-gallon hat becomes a 37.85 L hat).
