A cube is the familiar three-dimensional solid with eight vertices, six faces and twelve edges. I have been working with cubes recently in posts about both the Menger sponge fractal and the 4-by-4 matrix from computer graphics.

ContentsVertices Edges Wireframe FacesVerticesCartesian coordinates, V, for the eight vertices of a cube can be generated from the binary representation of 0:7.
