How many pairs of parallel edges does a rectangular solid have?

How many do you see?

I see 12

But the question asks about PAIRS of edges.

So it's 6?

I see 6 :)

345ytyty

I see 8.

I need a shape with 1 pair of parallel edges

It's 18. It never said they had to be congruent edges.

I solved this question when I was literally 6.

Check it yourself. Also, if you think I mean 9, I mean 18. It isn't a typo.
