Based on the diagram below, rank the three objects from least dense to most dense.

We are not given the diagram needed for this question so it would be better to talk about how to determine which object would be the most dense and least dense. One way to determine this is by looking at the densities of these objects. Higher value means the most dense while the lower value is the opposite.
