Chapter 1
1. (p.15 Prob.44) Computer chips are etched on circular silicon wafers of thickness 0.600mm that are sliced from a solid cylindrical silicon crystal of length 30cm. If each wafer can hold 100 chips, what is the maximum number of chips that can be produced from one entire cylinder?
2. (p.15 Prob.47) An average family of four uses roughly 1200 liters (about 300 gallons) of water per day. (One litter = 1000cm3.) How much depth would a lake lose per year if it uniformly covered an area of 50 square kilometers and supplied a local town with a population of 40,000 people? Consider only population uses, and neglect evaporation and so on.
