the question is much more complex.

Let us place a cube on a table and fix the cube. Consider 4 vertical edges = 4C2 = 6 pairs. Consider 4 horizontal edges = 4C2 = 6 pairs. Consider 4 frontal edges = 4C2 = 6 pairs. Thus, overall, there are 6*3=18 pairs of different parallel edges.

The answer is 4C2 * 3 = 18

There are four edges that are parallel in each "direction": up/down, left/right, front/back. Take a combination of two of these in every direction and you get 18.
