Gold can be hammered into extremely thin sheets called gold leaf. An architect wants to cover a 100 ft× 89 ft ceiling with gold leaf that is five-millionths of an inch thick. The density of gold is 19.32 g/cm3, and gold costs $ 953 per troy ounce (1 troy ounce = 31.1034768 g). How much will it cost the architect to buy the necessary gold?
