Question:

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 3.379 g, is pressed into a leaf of 8.880 ?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 2.900 ?m, what is the length (in m) of the fiber?
