Perhaps the author of the previous answer could explain his working.
It seems to me that there are two diagonals on each face (total 12), plus 4 internal diagonals, giving an answer of 16.
A cube has four space diagonals. One from each of the four vertices on the top face of the cube to the opposite vertex on the other face
The angle between two opposite space diagonals of a cube is 60 degrees. This can be determined by considering the geometry of the cube, where the space diagonals connect opposite vertices. Using vector analysis, the cosine of the angle between the diagonals can be calculated, leading to this result. Thus, the angle between any two opposite space diagonals in a cube is consistently 60 degrees.
It has 9 diagonals
It has 2 diagonals
9 diagonals
A cube has four space diagonals. One from each of the four vertices on the top face of the cube to the opposite vertex on the other face
I would assume the answer is 12, as a square has 2 diagonal lines, and a cube is really just six squares.
The side of a square is is cube root of 2cm. Find the length of the diagonals.
60
The 2 diagonals bi-sect each other at right angles which is 90 degrees
It has 1,345,890 diagonals
24 diagonals
It has 2 Diagonals!!!

There are 20 diagonals
20 diagonals
It has 27 diagonals
