5) King Krator the Merciless has called on Pogo, a humble goldsmith, to make a crown for theKing. He gives Pogo exactly 14 oz of pure gold to fashion the crown and tells him that if hecheats the King, he will pay with his life ! Pogo leaves with the gold; he and his apprenticesspend two weeks in making the crown; finally he returns to the court. When Pogo returns withthe crown, King Krator finds that the crown weighs 397.25 grams, and has a volume of20.58cm3. King Krator asks the court wizard for the density of gold, and Wizard tells the Kingthat gold has a density of 19.3 times that of an equal volume of spring rain. Krator demands aslate, makes a few calculations, then sternly lifts his head to stare at Pogo. Does Pogo's headroll ?
