According to legend, to determine whether the king's crown was made of pure gold, archimedes measured the crown's volume by determining how much water it displaced. the density of gold is 19.3 g/cm3. if the crown's mass was 600 grams, what volume of water would have been displaced if the crown was indeed made of pure gold?

There is an old story about a king and his crown. the king hired a goldsmith to make him a crown a pure gold. after the king received the crown, he started to worry that the goldsmith might have cheated him. he thought maybe the goldsmith didn't use pure gold, maybe he used a mix of metals to save money. the king asked a man named archimedes to figure out if the crown was pure gold or not. archimedes reasoned that the density of a lump of gold and a crown of pure gold would be the same. how could he prove if that crown was pure gold without melting or otherwise destroying the crown?

It is said that archimedes discovered his principle during a bath while thinking about how he could determine if kinghiero‘s crown was actually made of pure gold. while in the bathtub, he conceived the idea that he could determine theaverage density of an irregularly shaped object by weighing it in air and also in water. if the crown weighed 3.20 kgf (=31.4 n) in air and 295 kgf (= 28.9 n) in water, determine if the crown is made of pure gold. the density of gold is 19,300kg/m3. discuss how you can solve this problem without weighing the crown in water but by using an ordinary bucket withno calibration for volume. you may weigh anything in air.
