Although aluminum foil is very thin, it does have some thickness. We cannot typically “measure” the thickness of such a thin object directly, but the thickness can be determined “indirectly”. Assume that the density of aluminum is 2.70 g/cm3 and that the shape of the square aluminum foil is a rectangular cuboid.  Then by using the experimental data of the length of the aluminum square 5.10cm, Width is 5.00cm and the mass of aluminum is 0.11g. Determine the thickness of aluminum foil in micrometers. Show your work.
