okay guys. need some help with this one. its from Crack DAT PAt (haha like crank dat soulja boy). okay sorry bad joke anyways its attached as a work document

mostly i'm confused with wtf is going on with those half cube/triangle bits

thanks

There is definitely something wrong with that image, some lines are missing haha. Even still I dont think the answer is 3.

Im guessing thats an error, i dunno. what does everyone else think...
 
yea lines missing... I have crack the PAT and I think its great practice but the cube counting section is TERRIBLE!!! There are tons of images like the one you showed with missing lines and floating cubes. Its a good thing that this is probably the easiest type so you can get away with less practice from the other resources

Man, this stuff is blowing my mind.

There were 3 questions on this figure - the answers are as follows:

3 CUBES have 2 sides exposed
7 CUBES have 3 sides exposed
4 CUBES have 4 sides exposed
 
im pretty sure the image is correct

the image is actually an illusion. it can easily b misconstrued for something else. im going to try drawing a birds eye view of the image and post it up later on the thread; when i did it i got it right
 
Wow, that's hard to see...it's almost like the cubes are floating...Did m.c. Escher draw that?

So can anyone say if the top score cube-counting, hole punching, and angle rankings are close to the real DAT. That seems to be the only thing I can do out of the whole test...:laugh:😱

not really. if i recall correctly it wasnt that bad. some of em are pretty bad though. i think achiever is more similar than crack dat pat

I dont think the redraw picture is correct though
 
The picture is correct, it is just at a tough angle. Wait until you do test 10, there is one that is clearly wrong.
 
i think the picture itself is flawed. it shouldnt look like that and the cubes themselves are drawn poorly and dont represent what they will look lik eon the DAT
 
I took the DAT last year and cube-counting was fairly straightforward... unless they changed it a ton, there were definitely no optical illusions! I think CrackPAT is really good for practice, but don't freak out if you can't make sense of their weird cube counting... I don't think it's representative of the real test. Just my thoughts, hopefully the test hasn't changed too much since Sept.
 
there's nothing wrong with the cubes in that one - it's just that if you don't focus on it properly it'll appear like there's some cubes that are floating and/or cut in half
 
You just have to learn how to look at the image correctly..

Crack dat pat's cube counting made my heard hurt at first.. but once you get used to it, you'll be able to tell which cubes are in which plane.
 
GUYS!!!!!!!!!!!! THERE IS NOT "GLITCH" OMG!!!! Yes I know what your saying.....the 2 stacked cubes on the end......the one next to that looks like a "tunnel".......but look closely and focus. Check out my picture, hope it helps.

omagad!! chill man, it is definitely a difficult cube counting and i still believe there is an error. on the far left of the drawing on the second row there is a line that shouldnt be there. i erased it, so the new image would be the correct one IMO... what does everyone think?

I went through the documents you guys attached. It seems like everyone has a different interpretation of the question. I just took this exam so i am very interested in what you guys think. I got the whole thing wrong by the way. Can cubes be floating or do they have to cubes underneath that go to the ground floor? Do we assume there is a cube in the second row, one back?

NO, cubes cannot float. The only time there will be an "invisible" cube is if it is supporting a visible one. For example, there is a cube supporting the one you mentioned. Every other cube will at least have some part visible (even if it is a little corner).

what was causing so much cofusion on this one was the line i erased. IMO, that line made the drawing difficult to interpret since you should not be able to see through that cube.

does anyone see the line i erased?? should that line be there or not? did it help anyone?? 😕

I agree with your correction....That what I thought too. saaz55 redraw picture from the top view, I dont think it's correct though. The position of the cubes are off. Mikecueca is correct

there's nothing wrong with the question - look at DrHoya's document, it makes perfect sense

Your 'corrected' picture is wrong because your structure isnt continuous any more
 
here, i outlined the stacks in the problem area in different colours

the blue and teal stacks are 2 blocks high, the red, green, and pink stacks are 1 block high

Alright! Sometime finally sees what I see! There is no "glitch".....you just have to focus..All of the cubes are on the ground floor except (3 instances with 1 cube on top, and 1 instance with 4 cubes on top). If you look quick.....the stack of 2 highlighted in blue above, looks like the same level as the single stack in red, because the cube in purple and green (both on ground) seem to form a "tunnel" with the red cube.
 
Sama951 can you explain why the pink is one cube, its on the same level and the same "row" as the blue, i dunno maybe my eyes are playing tricks on me

The purple and green are on the same plane (ground) as the red.

it only looks like it's on the same level/row - but keep in mind that it's two spaces to the back-right and one space to the back-left - being back there might make it look like its on the same level as the blue one.

Also it's the same height as the red one beside it
 
Alright guys, here is a new pic that should put all myths to rest. In the attached pic, the cubes outlined in Black are on the ground, the cubes outlined in blue are on the second level, and the cubes in green constitute the rest of the tallest stack.

wow, i totally see that now. that row goes so far back (and to the left) that the far cubes look like they are on the second level.

good stuff!
 
yeah wow ... i finally see it now. I have taken this practice many times thinking it was an error. Thanks!!

I'm glad you guys see it. There are others like this on Crack PAT, and let me tell you, they are not errors. Don't underestimate cube-counting lol. 👍

still dont see it...please bold the cube like I did and tell me where that side belonged to

I typed an explanation in your drawing man. I hope it helps. If not, view my other pics above. You just have to see it once, then it will click.:idea:.

thanks you guys are genius!!...It only 1 level, I thought I two level....

got it thanx DRHOYA and Sama951 👍

btw will they ask something like this in the DAT? the optical illusion type of questions?
 
Just so you guys know, there is none of this nonsense on the actual DAT. I did not have one cube counting that had more than like 15-17 cubes and the angle of the picture make it very clear how the cubes are oriented. Crack's cubes are trying too much to trick you with illusions, not necessarily testing you on tough perceptual layouts.

i had one. it looked like a row of single high blocks went from 3 across in the back of the figure and moved inward to only 2 across in front - like a trapazoid with the long side away from you and the small side coming at you.

Thats good to know, but the thing is with Crack PAT, they can sometimes be so hard, but when you get "normal" ones, its like a relief. Oh well, I guess I'll find out end of July😀
 
I would say simply move on to the next question. There is something wrong with this drawing. Don't worry!

I stand corrected! 😳

Wow, Im sorry I didnt know the cubes had to be continuous! thanks a lot, it makes sense now. verrrry tricky

Wrong.

There was a question like this on my DAT, almost exactly the same (diagonal line in the middle of a cube, making it look like an illusion). I was so confused as to what was going on.
