    A cube layer is a one-cubie-thick slice of the cube perpendicular to its axis of rotation. Outer layers (faces) contain more cubies than inner layers. For a cube of size , there will be layers along any given axis. Cube face The meaning of a cube face depends on the context in which it is used.

    Geometric shape: hexeract (6D) and hepteract (7D) 7-cube 5 7 virtual puzzle, scrambled. Andrey Astrelin's Magic Cube 7D software is capable of rendering puzzles of up to 7 dimensions in twelve sizes from 3 4 to 5 7. As of July 2024, in terms of puzzles exclusive to Magic Cube 7D, only the 3 6, 3 7, 4 6, and 5 6 puzzles have been solved. [5]

    John Locke, an 18th-century philosopher, speculated that if a blind person developed vision, he would not at first connect his idea of a shape with the sight of a shape. That is, if asked which was the cube and which was the sphere, he would not be able to do so, or even guess.

    en.wikipedia.org/wiki/Mirror_blocks

    The Mirror Blocks, also known as the Mirror Cube and Bump Cube, is a type of combination puzzle and shape modification of the standard 3×3×3 Rubik's Cube and was invented in 2006. The puzzle's internal mechanism is nearly identical to that of the Rubik's Cube, although it differs from normal 3×3 cubes in that all pieces are the same color ...

  8. Cube - Wikipedia

    en.wikipedia.org/wiki/Cube

    The cube is non-composite polyhedron, meaning it is a convex polyhedron that cannot be separated into two or more regular polyhedrons. The cube can be applied to construct a new convex polyhedron by attaching another. [40] Attaching a square pyramid to each square face of a cube produces its Kleetope, a polyhedron known as the tetrakis ...

  9. Snub (geometry) - Wikipedia

    en.wikipedia.org/wiki/Snub_(geometry)

    Two chiral copies of the snub cube, as alternated (red or green) vertices of the truncated cuboctahedron. A snub cube can be constructed from a rhombicuboctahedron by rotating the 6 blue square faces until the 12 white square faces become pairs of equilateral triangle faces. In geometry, a snub is an operation applied to a polyhedron.
