"""Three images are shown. The first image shows a cube with black dots at each corner and red dots in the center of each face of the cube while the second image is composed of eight spheres that are stacked together to form a cube with six more spheres, one located on each face of the structure. Dots at the center of each corner sphere are connected to form a cube shape. The name under this image reads """"Face-centered cubic structure."""" The third image is the same as the second, but only shows the portions of the spheres that lie inside the cube shape."""
