What is Cube?
[[File:Cube.svg|thumb|A cube has 6 sides of equal length and width]] [[File:Selpologne.jpg|thumb|A magnified crystal of salt]] A '''cube''' is a type of [[polyhedron]] with all [[right angle]]s and whose [[height]], [[width]] and [[depth]] are all the same. It is a type of [[cuboid|rectangular prism]], which is itself a type of [[hexahedron]]. A cube is one of the simplest [[Platonic solid|mathematical shape]]s in space. Something that is shaped like a cube can be called ''cubic''. Surface area of cube=6l^2 Lateral Surface area of cube=4l^2 Volume of cube=l^3 [[File:Hexahedron.gif|thumb|A [[rotation|rotating]] cube.]] == Relative 2-dimensional shape == The basic difference between a cube and a [[Square (geometry)|square]] is, a cube is a [[3D]] figure (having 3 [[dimension]]s) i.e. length, breadth and height while a square has only 2 dimensions i.e. length and breadth. The 2-dimensional ([[2D]]) shape (like a circle, square, triangle, etc.) that a cube is made of is [[square (geometry)|squares]]. The sides (faces) of a cube are squares. The edges are straight [[line]]s. The corners (vertices) are at right angles. A cube has 8 corners, 12 edges and 6 faces, as in the most usual kind of [[dice]]. A [[tesseract]] carries this idea into the fourth dimension ([[4D]]) and is made of 8 cubes. == Volume == * The [[volume]] of a cube is the [[length]] of any one of the edges (they are all the same length so it does not matter which edge is used) ''cubed''. * This means you multiply the number by itself, and then by itself again. * If the edge is named 'd' (See Diagram), the equation would be this: Volume=d×d×d (or Volume=d<sup>3</sup>). == Cube-shaped figures == * [[Dice]] * [[Box]]es {{shapes}} [[Category:Platonic solids]]
