How many perpendicular edges does cuboid have?

Answer 1

A cuboid has 12 edges, and each edge is perpendicular to 4 other edges. Specifically, for each of the three dimensions (length, width, height), there are 4 edges that are perpendicular to the edges of that dimension. Thus, while there are many pairs of perpendicular edges, the total number of perpendicular edges can be considered as 12 in the context of their relationships with one another.
