A cube has six sides, which are also called faces. There are four faces on the sides of the cube, and the top and bottom each have one face. An example of a cube is a standard die with sides numbered from one to six.
A cube also has eight vertices and 12 edges. A vertex is a corner that joins edges together; therefore, the eight vertices are located at the corners. Half of the vertices surround the top face, and the other half border the bottom.
A cube is a unique three-dimensional shape because all six of its faces are the same size and shape.
