Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³). It is a physical property that helps determine how heavy an object is for its size. In this context, the gray cube has a density of 4.5 g/cm³, which means it is relatively heavy for its volume compared to other materials.

Comparison of Densities
When comparing the densities of two objects, one can determine which is heavier or lighter for the same volume. If the green cube's density is less than 4.5 g/cm³, it will be lighter than the gray cube; if it is greater, it will be heavier. This comparison is crucial for understanding the relationship between the two cubes in the question.

Material Properties
Different materials have characteristic densities that can influence their physical properties and applications. For example, metals typically have higher densities than plastics. Understanding the material composition of the green cube, even if not explicitly stated, can provide insights into whether its density is likely to be higher or lower than that of the gray cube.
