Answer:
a) 28
b) 56
Step-by-step explanation:
A cube is a three dimensional shape gotten from a square. It has 6 faces, and an equal line segment that form its sides.
A vertex is the edge of a figure.
In the given cube ABCDEFGH, since the vertices to be considered are not only the adjacent vertices, then;
a) By connecting the vertices of the cube, 28 different segments can be obtained.
b) The number of triangles that can be formed by connecting 3 of the vertices of the cube is 56.
