1 Two student, Lee and Melanie, each hold a solid object. Lee has solid object A and Melanie has solid object B. The students make the following observations:
Larry: "My object has three times the mass of object B and since density is directly proportional to mass, my object has 3 times the density of object B."
Melanie: "My object takes up 1/3 of the volume of object A, and since density is inversely proportional to mass, my object is 3 times as dense as object A."
a) which student, if either, is correct?
b) If the statements about the mass and the volumes of each object are correct, how do the densities of each object compare?
