A king ordered a new crown to be made from pure gold (density = 19200kg/m3). When he received the crown he suspected that other metals may have been used in the construction. Archimedes discovered that the crown needed a force of 20.91 N to suspend when submersed in water and that is displaced 3.1 x10^-4 m3 of water. He concluded that the crown could not be pure gold. Do you agree or disagree?
