What is the primary purpose of work flow analysis in lean methodology?

A golden-colored cube is handed to you. The person is saying that it is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You also read that the density of pyrite (a.k.a. fool’s gold) is close to 4.75 g/cm3. You measure the cube and find that it is 1.55 cm on each side, and weighs 71.796 g. a) What is its density in g/cm3? b) What is its density in g/ml? c) Is it gold or pyrite? Show all your work. Use units and correct number of significant figures.
