Gold can be hammered into extremely small sheets called gold leaf. If a 200-mg piece of gold (density = 19.32g/cm cubed) is hammered into a sheet measuring 2.4 x 1.0 ft, what is the average thickness of the sheet in meters? How might the thickness be expressed without exponential notation, using an appropriate metric prefix?

Thats a toughy. I refer you to www.infowars.com for that one. You need to listen to Alex Jones.

Thickness = Volume/area

The dimensions in cm are 73.2 x 30.5. Total area is 2230 cm^2.
Total volume is 0.200 / 19.32 = 1.04E-2 cm^3
Height of sheet = V/A = 4.62E-6 cm = 46.2 nanometers
