I don't know how to go about doing this Chemistry problem.

Therefore Vol. of Al foil = mass/density = 3.736/2.699 = 1.As area = 1.000ft^2,......
HELP ME PLEASE D:

A sheet of Aluminum (Al) foil has a total area of 1.000ft^2 and a mass of 3.736 g.
What is the thickness of the foil in millimeters (density of Al = 2.699 g/cm3 )

-
As density = mass/Vol
Therefore Vol. of Al foil = mass/density = 3.736/2.699 = 1.384 cm3
As area = 1.000ft^2, change it in cm2. Then divide the vol. by area you will get thickness in cm, multiply that by 10 you will get in mm.
