How many cubes there are in attached file?

Would you expect something disguised like this in actual DAT? IMO, No. What's your answer?

I have 15 cubes. I believe One is hidden from view by the pillar. I don't know why but it just sees to be too much space between that not to have a cube.

let me guess CDP?
 
Wow i just did this CDP test 15 min ago and was wondering the same thing. I guessed that there were only 14 and that was correct. So I used that to determine what was shaded and what was not. I hope there are no illusions harder than this on the real DAT.

There are 15 cubes in it.

The one behind the pillar all the way to the end was not the problem for me. You could see you need the cube to fill that gap otherwise 2 part of the figure won't be connected. It was kind of indicative.

Problem was one immediately behind the pillar. Please see in attached new file.

There is no clear indication whether its cube there or just the empty space. I mean you could take it either way and you will have different answer. Both way will be correct so the point is...should we expect to be something like this real DAT?

My understanding of standardized test that they don't have something in GRAY area...for example total ATP -- technically its range..you can't say its 36 which Kaplan say or may be some other commercial book beside text book. Total ATP production varies from cell to cell and IMO, even from one person to other. But hey..for DAT its 36 !!! I'm wondering if anyone here has that question in there actual DAT...my guess No..cause it's gray area..there is no one answer to the question unless you phrase the question accordingly like "maximum amount of ATP in one cycle" or something like that.

wow..I went totally off the subject..anyways..this is just the way I think..thought to share with you guys here.

I only see 14 cubes.. can you please tell me where is the 15 one that I am missing..

Please see attached document that corresponds to each cube.. due to the size limitation of an attachment on this forum i am not able to include the figure... however, if you copy paste the figure from the pdf attached in this thread.. these numbers will correspond to each cubes..

if there is any issue please tell me where i can upload my 1.something MB file..
 
Oops forgot the attachment..

here it is..

I got 14 too. I have no idea how you guys are getting 15. It does not seem that tricky either. I don't see how anything could be hidden?

What did the answer key say? 14 or 15?

Oh, I get it now. This is the top view.

The red box is the pillar. Notice that 1, 2, 3 in the first pic are together in a straight line. Then 4, 5 go back. So they are behind the pillar and then there is a box you can't see connecting to 14.

So did the answer key say 14 or 15?

Something is wrong with this picture. It doesn't seem like it's to scale. I'm referring to the bottom row, 3 cubes on the left and 2 cubes on the right separated by a space. There's not enough room to fit 2 cubs in that space yet the space is too wide for just one cube.
 
What exactly are we confused about? I don't understand..

Let me know and I can try to clarify for you.
 
If you look at the explanation on CDP after you take the test there are 14 cubes in the diagram. There is one hidden but some are counting one block twice, so it looks like there is 15 instead of 14. Undergradguy7 labeled one block twice as number 13 and 14 on his post. That is one block there according to the key on CDP.
 
Which test # does this come from? Someone shoudl just screencap the explanation where they highlight the cubes.

undergrad7 has #13 as a cube between the pillar and what is #14. its the cube above the red one in his top view drawing.

So if the explanation calls it an illusion I'm gonna chalk it up that the real DAT isn't gonna have something like this.

there's no way to realistically tell whether its an empty space or a cube there.
 
It is test #2, and I agree it could go either way like herkulease said most likely not on the DAT. This question is rather tricky. I will email CDP and ask them to clarify.

If everything is connected then there has to be a cube where 13 is (and it not being 14)?

yeah if its all connected then yeah I agree there is a cube where you put 13.
from what those who've done test #2 on cdp the answer say its an empty space where you have 13 and CDP calls it an illusion. I have done test #2 yet. so I don't want to pull it up merely to see.

as i said there's really no way to tell from the figure its an empty space or a cube there.

I'm gonna assume the real DAT doesn't have something that's a gray area and open to debate.
 
I don't think that all squares must be connected. I think that when a block looks to be hidden by a pillar as in a case such as this, you are suppose to assume that there is no block there unless another pillar was visible behind the pillar that is in the picture. In other words if the block that you think is invisible is not holding any other blocks that you can see you are suppose to act like there is not a cube there. Which would mean that the answer is 14 sorry if this sounds confusing. :laugh:
 
As far as I remember, the actual rule on cube counting states that all the cubes must be connected.
 
what is connected defined as though? Do they have to be connected face to face, or is edge to edge connection enough as in this example?

Face to face. Corners touching does not count as a connected cube. If that cube does not exist in the back, it would be 2 different structures. Also, the one labeled 13 "should" exist because otherwise it would be disconnected (since corners don't count).

I'm 95% sure that is the case. Someone else can confirm.
 
There are no edge connections on the sample test, there weren't any on my exam, and the instructions say they are made by "cementing together." It's kinda hard to cement together two cubes on only their edges.
 
There would only be 2x2x2 unpainted cubes. What's up with this question from a first-poster anyway? 😕
 
the most you can visually see is 14... if it did say "assume all blocks are connected" like tinman said, then you probably could infer that there are 15

They don't have to say it. It's implied that you need that 15th block for the entire piece to be cemented together. They also don't explicitly say you can only fold in on the pattern folding section, but it's implied when they say the outside pattern is what you see..

Rest assured there will be no "should there be a block there?" instances on the real exam.
