A sphere lacks edges. Edges are associated with faces and are found in shapes like squares and rectangles. Because of the round shape of a sphere, it lacks faces.
Edges interconnect the faces of an object. A cube is a prime example of a geometric figure containing multiple faces. A cube possesses a total of 12 faces. A sphere is defined as a round, three-dimensional geometric figure in which every point of the surface of a sphere is equidistant from the center. A sphere differs from a circle because a circle is not three-dimensional. A ball is the standard example of a sphere.
