O MATTER Solving applied density problems Mr. Auric Goldfinger, criminal mastermind, intends to smuggle several tons of gold across international borders by disguising it as lumps of iron ore. He commands his engineer minions to form the gold into little spheres with a diameter of exactly 6 cm and paint them black. However, his chief engineer points out that customs officials will surely notice the unusual weight of the "iron 3. ore" if the balls are made of solid gold (density 19.3 g/cm). He suggests forming the gold into hollow balls 3. instead (see sketch at right), so that the fake "iron ore" has the same density as real iron ore (5.15 g/cm). One of the balls of fake "iron ore," sliced in half. Calculate the required thickness of the walls of each hollow…
