For Exercises 49, refer to the table on page 551. rlock Holmes rushes home to his chemistry lab, takes a mysterious medallion from his case, and weighs it. It has mass 3088 grams. Now lets check its volume. He pours water into a graduated glass container with a 10-by-10 cm square base, and records the water level, which is 53.0 cm. He places the medallion into the container and reads the new water level, 54.6 cm. He enjoys a few minutes of mental calculation, then turns to Dr. Watson. This confirms my theory. Quick, Watson! Off to the train station. Holmes, you amaze me. Is it gold? questions the good doctor. If it has a density of 19.3 grams per cubic centimeter, it is gold, smiles Mr. Holmes. If it is gold, then Colonel Banderson is who he says he is. If it is a fake, then so is the Colonel. Well? Watson queries. Holmes smiles and says, Its elementary, my dear Watson. Elementary geometry, that is. What is the volume of the medallion? Is it gold? Is Colonel Banderson who he says he is?
