QUESTION:

A thief uses a can of sand to replace a solid gold cylinder that sits on a weight-sensitive, alarmed pedestal. The can of sand and the gold cylinder have exactly the same dimensions ( length = 22 cm and radius = 3.8 cm ).

a. Calculate the mass of each cylinder (ignore the mass of the can itself). (density of gold = \(19.3 \ g/cm^3\), density of sand = \(3.00 \ g/cm^3\))

b. Did the thief set off the alarm? Explain.
