Yes, a cuboid does have parallel edges. In a cuboid, all pairs of opposite edges are parallel to each other. Additionally, the opposite faces of a cuboid are also parallel to each other.

I'm pretty sure it is 12 pairs of parallel lines.
3 sets of four mutually parallel lines.
Three sets of four each.
A cuboid has 3 quartets of parallel lines. Each quartet gives rise to six pairs. So, in all there are 18 pairs of parallel lines.

Parallel Lines. If they are in different planes, they need not be parallel. Think of a cuboid room. Line 1 is the edge formed by the floor and the wall opposite you. Line 2 is the edge formed by the wall behind you and the wall to your right. These two lines will not meet but they are certainly not parallel.
