there is 15 perpendicular lines in a cube
I believe they do, and they have 2 perpendicular lines.
a cube * * * * * It cannot be a cube because a cube does not have 8 pairs of perpendicular faces - it has 12.
yes,
Each of the 12 edges of a cube is directly perpendicular to four others (two at each vertex for that edge).
