and Dimensional Analysis

Follow the instructions below to make a series of measurements and calculations. You may work with a partner but everyone must write down the measurements and perform the calculations on their own paper. Use a ruler and meterstick/yardstick to make your measurements.

- Measure the length and width of a book cover in cm to the nearest 0.01 cm. Calculate the area in cm
^{2}. Write your measurements and calculations here. - Measure the same book’s length and width in inches to the nearest 1/16 of an inch. Calculate the area in in
^{2}. Write your measurements and calculations here. - Write your result
*from measurements*for the area of the book cover in cm^{2}. Convert it to in^{2}, showing your work for the calculation. - Write your result
*from measurements*for the area of the book cover in in^{2}. Convert it to cm^{2}, showing your work for the calculation. - Evaluate your results by comparing the area values from measurement to the values you obtained by converting from one unit to another.
- Why are they not exactly the same?
- Are they close enough to each other to prove that the conversion math is accurate?

- Measure the length, width, and height of a fish tank in m to the nearest 0.0001 m (1/100 of a cm). Calculate the volume in m
^{3}. Write your measurements and calculations here. - Measure the same tank’s using feet to the nearest 1/16 of an inch. You will have to convert feet and inches and fractions of an inch to decimal feet. Calculate the volume in ft
^{3}. Write your measurements and calculations here. - Write your result

- Measure the length of the room in feet or meters and write it here.
- Assume you walk at 2 mi/hr. Calculate the number of seconds it would take at this speed to walk the length of the room. Show work for your calculations here.
- Try it. Time yourself walking the length of the room. Write down your result here.
- Was your result close to your calculation? Why was it not exactly the same?
