The aluminum foil on a certain roll has a total area of 18.5 m 2 and a mass of 1275 g. using a density of 2.7 g per cubic centimeter for aluminum, determine the thickness in millimeters of the aluminum foil.

The thickness in millimeters of the is 0.02552.

Explanation:

Area of an aluminum foil = A =

Mass of the assuming foil = 1275 g

Volume of the aluminum foil = V

Thickness of the assuming foil = h

Density of the aluminum foil =

Volume = Area × Depth

1 cm = 10 mm

h = 0.02552 mm

The thickness in millimeters of the is 0.02552.
