: Not to be confused with Dimension of a physical quantity. For other uses, see Dimension (disambiguation). In physics and mathematics, the dimension of a space or Mathematical object|object is informally defined as the minimum number of coordinates needed to specify any point (geometry)|point within it. Thus a line (geometry)|line has a dimension of one because only one coordinate is needed to specify a point on it (for example, the point at 5 on a number line). A surface such as a plane (mathematics)|plane or the surface of a Cylinder (geometry)|cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its latitude and its longitude). The inside of a cube, a cylinder or a sphere is three-dimensional because three co-ordinates are needed to locate a point within these spaces. In physical terms, dimension refers to the constituent structure of all space (cf. volume) and...
