    if you don't count the center, it should be 12. With center is 13.
    center = core of the structure

    rules say if you cant see if a cube is there or not and there are no cubes that would be supported by it... it isnt there. If you cant see it but you see cubes that are supported by the possible cube it is there and you count it... so ya in the picture you should count 12 cubes

    What he means is if you look at it from the top view you should see this...

    [​IMG]

    The numbers represent how many cubes are stacked on each other.

    You guys are thinking that there is 2 cubes stacked on each other in each corner, which is incorrect according to the answer of 11 cubes.

    No, at first I saw it like them. Then read your comment looked back at it like one of those pictures you have to stare at to see it another way and saw it that way.

    I got fooled by this one too. From the explanation given, it's 12 cubes (there is no center cube).

    I posted a picture of how I see it... I see 11 cubes...

    Maybe why I didn't do well on PAT LOL

    The 11th cube is the depicted as the arrow in the picture (bottom of the tall stack)

    There arent questions like this on the DAT. The DAT cubes are all straight forward and easy. Ignore the "illusion" questions from CDP and just know the regular questions.
