Cubic Close Packing (CCP) is a method of arranging spheres in a three-dimensional space to maximize density. In this arrangement, each sphere is surrounded by twelve others, creating a highly efficient packing structure. This configuration allows for approximately 74% of the space to be filled with spheres, making it one of the most efficient packing methods. CCP can be visualized as layers of spheres stacked in a specific pattern. The first layer is placed flat, and the second layer is arranged so that the spheres fit into the gaps of the first. This stacking continues, forming a repeating pattern that is characteristic of face-centered cubic structures.
