In general, a diagonal is a line segment that joins two opposite vertices in a polygon having more than three sides. Diagonals are not present in a triangle. A Cube is a three-dimensional solid figure whose all three dimensions i.e. length, breadth, and height are equal in measurement. Some of the examples of cubes that we can see in our daily life are ice cubes, Rubik’s cube, and the die of Ludo, etc. A Cube has 6 faces, 12 edges, and 8 vertices. Apart from faces, edges, and vertices, there are diagonals inside a cube....
