Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber.

(a) If a sample of gold with a mass of 1.576 g, is pressed into a leaf of 5.271 ?m thickness, what is the area (in m2) of the leaf?

(b) If instead, the gold is drawn out into a cylindrical fiber of radius 2.400 ?m, what is the length (in m) of the fiber?
