In geometry, a cube is a three-dimensional strong object limited by six square faces, features or sides, with three meeting at every vertex.
A cube has 8 vertices. Number of line segments = 8C2=28. (As a line segment has 2 end points)
(1) Each line segment uniquely determines a pair of endpoints.
(2) Each pair of endpoints uniquely determines a line segment.
