6. At our house, we have a 10-in. frying pan and a 12-in. frying pan; the 12-in. one weighs a lot more, cooks food more slowly, and never gets as hot. Suppose that a 10-in. frying pan weighs 1 lb, apart from its handle. How much would a geometrically similar 12-in. frying pan weigh? How much would it weigh if it had the same thickness of metal as the 10-in. pan?
