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.
