This decomposition of a regular hexagon is based on a [[Petrie polygon]] projection of a [[cube]], with 3 of 6 square faces. Other [[parallelogon]]s and projective directions of the cube are dissected within [[rectangular cuboid]]s. {| class="wikitable skin-invert-image collapsible" style="text-align:center;" !colspan=12| Dissection of hexagons into three rhombs and parallelograms |- !rowspan=3| 2D !
