A Rubik's Cube has nine square facelets on each side, giving fifty-four facelets in total, and occupies a volume of twenty-seven unit cubes.
Typically, the faces of the cube are covered by nine stickers in six solid colors; there is one color for each side of the cube. When the puzzle is solved, each face of the cube is a solid color.
The cube celebrated its twenty-fifth anniversary in 2005, when a special edition cube in a presentation box was released, featuring a sticker in the centre of the reflective face (which replaced the white face) with a "Rubik's Cube 1980-2005" logo.
