Asheet of aluminum (al) foil has a total area of 1.000 ft2 and a mass of 3.636 g. what is the thickness of the foil in millimeters (density of al =2.699 g/cm^3)?

The thickness of the foil is 0.01450 mm

Explanation:

1 ft = 30.48 cm

So area of Al foil is

if thickness of foil is d cm then volume of Al foil is

We know,

Here density of Al is 2.699 and mass of foil is 3.636 g.

So volume of foil is or

So,

or, d = 0.001450

So thickness of foil is 0.001450 cm or 0.01450 mm
