Cube only member of that group that is a zonohedron (every face has point symmetry). The cube can be cut into six identical square pyramids. If these square pyramids are then attached to the faces of a second cube, a rhombic dodecahedron is obtained (with pairs of coplanar triangles combined into rhombic faces). The analogue of a cube in four-dimensional Euclidean space has a special name—a tesseract or hypercube. More properly, a hypercube (or "n"-dimensional cube or simply "n"-cube) is the analogue of the cube in "n"-dimensional Euclidean space and a tesseract is the order-4 hypercube. A hypercube is also called
Cosmic Cube the trio invaded a KubeKult base to steal the erratically functioning Cube but the Red Skull seized it and willed Captain America to be drawn inside it into an artificial reality during World War II, where Captain America and Bucky were on a mission to kill Hitler. The Red Skull believed that he would be able to wield the Cube's power only if Captain America killed Hitler's consciousness within the Cube.
