Cube Counting Illusion #3

Forgive me if this is a double post, I couldn't find anything on it as I searched.

I thought it was the one on the right but the answer key said it was the one on the left. Now I can see it either way.

Is there any way that you could determine that it's the left one from the rules of cube counting? Or is this one of those illusions that we don't need to worry about on the real DAT?

it is the one in the middle

Could you explain why it's the middle versus the right? I still see both as valid until someone can explain to me why it can't be the right one.

It just looks that one w/o any hesitation. I don't know how to explain it. May be you think it too much. The last one has 3 stories, which doesn't make a sense when you compare it with first one (which only has two stories)

Thanks for your explanation, I can see how it makes sense if you assume that you're starting with a 3x3 layout with a cube missing from the middle.

At risk of being 'that guy on SDN forums who goes on for 10 posts even though it's obvious he's wrong,' I have one last challenge:

How would #1 look different if it were supposed to be representing #3? If I were trying to draw #3 from the same angle as #1, I can't think of anything that I would do differently - so it seems like #1 could be either two or three.

Maybe I'm crazy. Regardless, thanks for your explanation.

I think either one could work. I think they just gave a bad example and had the middle one in mind when they made it.

At the end of the day, none of those "weirdos" show up in your test, so why bother? I just disregard them all and move on. You will be fine.

Reviving this dead thread because i have the same question. Can you really distinguish #2 and #3 from the picture? Do you just have to assume it is #2 because it would look more natural than #3?..

ninja edit: the kaplan course taught me that the phantom cubes hidden behind other cubes are not going to be there on the test. but CDP includes those cubes more often then not? i'm confused.
