1) By Equation. You will use both above equations.
a) You will find the Volume (V) of the foil using the Density equation. (Remember, need to modify equation above so that volume (V) of foil is on one side of equation and all other variable are on opposite side before you plug in numbers). Keep that calculated value with one more sig figs (N+1) than you need in answers.
b)You will find the thickness (Th) of the foil by using the Volume equation for a solid rectangular. (Remember, need to modify equation above so that thickness (Th) of foil is on one side of equation and all other variable are on opposite side before you plug in numbers).
2) By Dimensional analysis Using the information in Data table and your knowledge of DA, show all work on determining the thickness (Th) of the foil. Remember, you only do "one" DA "string" to determine Thickness.
Questions/problems
1) Print out (unless it is handed out already) Question for Thickness of Aluminum Foil Lab.
Remember, you need to provide a paraphrased version before answering questions.

1) Why couldn't you use a centimeter ruler to measure the thickness of the aluminum foil?
2) What would you say to a person that recorded the length of her aluminum foil as 3.4575cm after measuring with a ruler marked to the nearest millimeter (mm)?
