{{anchor|Compound of cubes}}Compound of cubes is the [[polyhedral compound]]s in which the cubes share the same centre. They belong to the [[uniform polyhedron compound]], meaning they are polyhedral compounds whose constituents are identical (although possibly [[enantiomorphous]]) [[uniform polyhedra]], in an arrangement that is also uniform. Respectively, the list of compounds enumerated by {{harvtxt|Skilling|1976}} in the seventh to ninth uniform compounds for the compound of six cubes with rotational freedom, [[Compound of three cubes|three cubes]], and five cubes.{{r|skilling}} Two compounds, consisting of [[compound of two cubes|two]] and three cubes were found in [[M. C. Escher|Escher]]'s [[wood engraving]] print [[Stars (M. C. Escher)|''Stars'']] and [[Max Brückner]]'s book ''Vielecke und Vielflache''.{{r|hart}}

{{anchor|Spherical cube}}The spherical cube represents the [[spherical polyhedron]], which can be modeled by the [[Arc (geometry)|arc]] of [[great circle]]s, creating bounds as the edges of a [[spherical polygon|spherical square]].{{r|yackel}}
Hence, the spherical cube consists of six spherical squares with 120° interior angles on each vertex. It has [[vector equilibrium]], meaning that the distance from the centroid and each vertex is the same as the distance from that and each edge.{{r|popko|fuller}} Its dual is the [[spherical octahedron]].{{r|yackel}}

The topological object [[3-torus|three-dimensional torus]] is a topological space defined to be [[homeomorphic]] to the Cartesian product of three circles. It can be represented as a three-dimensional model of the cube shape.{{r|marar}}
