So you CAN'T use your ruler to measure thickness or height of the foil, which means that you can't use the equation LxWxH to get the volume of the foil in cm³.
However, If you knew the ___________ and the conversion factor __________, then you could calculate the volume of the foil.

• area , 1 mL/cm³

• mass, 1000cm³=1L

• mass, density

• 1.6 km/mi, mass

Density or any "per" statement is a conversion factor. The density of aluminum is 2.70 g/cm³ which you should RE-WRITE as an equivalence or 2.70 g = 1 cm³
What is the volume for a piece of HD aluminum with a mass of  1.03 g 

• 0.38 cm³

• 2.62 cm³

• 1.67 cm³

• 2.78 cm³

Now that you know how to determine the thickness of a piece of foil by applying:density, mass, and the equationV=LxWxH ......Go to the space below your data table and perform the same calculations from problems #7 and #9 above, but with the data for your piece of foil!

• Did it and my #'s are correct.

• Oops! I fat fingered that one.
