Determining Aluminum Foil Thickness Lab

Two common concepts used to measure the thickness of a small rectangular piece of aluminum foil:
1. Volume of a rectangular solid V=  Length × Width × Height
2. Density of a substance D= Mass / Volume

Calculate the volume of your aluminum piece.
Use the density formula, D = mass/volume for this. Solving for V gives
V = mass / density
(Volume of foil = ________ cubic centimeters = ______ ml)
Note: 1 cubic centimeter occupies the same volume as 1 milliliter.
Round your answer to match the origincal measurement that had the fewest significant digits.
(Volume after rounding for significant digits = _________________ ml)
Calculate the thickness of your aluminum.
Use the formula of a box, V = length x width x height
solve the formula for height, which represents the thickness of the aluminum foil in cm.
(h = _______________ cm thick)
Round your answer to match the original measurement with the fewest significant digits.
(Thickness after rounding significant digits = __________________ cm.)
