Ireally do not understand. you have 2 cubes (cube a and cube b) that are the exact same size. the only thing that is different about them is their densities. cube a has a density of 1.44 g / cm3, while cube b has a density of 2.37 g / cm3. how is it possible that the blocks have different densities even though they are the exact same size? someone me.
