Explanation
Here we need to calculate the ratio of densities of two cubes, Cube A and Cube B. Density is mass divided by volume. Assuming that cube A and cube B are identical in dimension, and knowing that the volume of a cube is a constant for identical cubes, the density comparisons become entirely dependent on mass comparisons.Therefore, the ratio of the cube A's density to the cube B's density is merely the ratio of cube A's mass to cube B's mass.
