  1. sabrina says:

    D

  2. Erik says:

    Must be D, but I can’t see why C doesn’t work also.

  3. Victoria says:

    Answer: D

  4. tester says:

    hmmm… sory, but C and D are equal…

  5. Alvaro says:

    Answer: both C and D are correct. Great work!

  6. Senia says:

    I like this one! Can you give us more of these?!
    Thanks.

  7. Alvaro says:

    OK, will get more!

  8. Scott says:

    I was confused between C & D at first but then noticed the side with the triangle does not meet the rest of the box on the right axis.

  9. shounak says:

    reply is A

  10. shounak says:

    d is correct

  11. sebas says:

    it is a,c,and d

  12. g says:

    Both C & D… only C & D.. Scott, there is no difference with the triangle… download the image and rotate it, or better yet, cut them out of paper. C & D both work. A&B Fail however because the double lines do not run towards the circle when folded.

  13. JOse says:

    en realidad la unica que no encaja es la A… al rotar y colocar la B-C-D el resultado es la imagen en cuestion.

  14. craig says:

    the ans is d

  15. John says:

    Alvaro, I don’t know if my browser if warping the image, but unless what I’m seeing has been stretched vertically from the image you’re working from, the answer can only be D. Is this supposed to be a cube?

  16. Alvaro says:

    Hello John, yes, this is supposed to be a cube. Doesn’t C work for you, as well as D?

  17. me says:

    c and d

  18. Mitch says:

    C & D are both correct, i spent like 10minutes trying to work out how 1 of them was wrong. But no they are both correct, and the ONLY correct answers.

  19. miss says:

    i got c

  20. manash says:

    BOTH ‘D’ AND ‘C’ARE CORRECT

  21. ***mOny*** says:

    Oh!!! Hi !!!

    I think the answer is the letter D.

    Bye
    See you !!!
    :P

  22. mackkk says:

    D and… only D – C seems same but one never makes a cube out of C ..try ;)

  23. mackkk says:

    why? well because in fact it’s not a cube but a cuboid :)

  24. Linda says:

    C & D

  25. Linda says:

    Thanks, mackkk. It is only D.

  26. Aaron says:

    It’s D, not too hard :)

  27. Anna says:

    it’s D, this one wasn’t hard

  28. Mukesh says:

    it is C only the correct one

  29. Travis says:

    I don’t see how “C” is correct, and lacking Photoshop and a printer, I don’t have any way of verifying this. Can someone explain the folds required to make the block?

  30. Abel.... IQ of 135 says:

    i only see D really clearly.. but i haven’t tried to vizualize C… C has a 60% chance of being correct as well.. from my view. D has a 100 % chance. – ABel was here.

  31. Cal says:

    C and D are correct.
    You have to rotate C in three dimensions for it to fit but it does ;)

  32. Theofanis says:

    It’d (D) because when you build the box to be exactly like the original you ‘ll turn it 180 degrees and then, above the circle you will see the white hedra and not the black n white that is near the two lines

  33. anthonette says:

    C and D
    =)

  34. Ishan says:

    C & D

  35. Ryan says:

    D only if you’re not supposed to flip it, both C and D if you’re allowed to flip it.

  36. Tarrence says:

    D. C doesnt worklk because the triangle would be on the side, not the top….

  37. Behrooz says:

    It’s D. Can’t be C, just look at the parallel lines. They aren’t 90^ to the circle.

  38. Kaitlin says:

    The answer is D
    C cannot work because of the way it was cut out. if you were to try to build the box with the way C is cut, you would not get a cube.

  39. emina says:

    I’m pretty sure that C and D are both applicable.☺

  40. Craig says:

    all of the shapes there can be folded into cubes… it is a statement “The box pictured here has been folded together from one of the four choices given. Which one?” A misleading question for sure… since C and D can both work for this.

  41. Alex says:

    It cant be “C” b/c when you try to make a square out of it you will get a duplicate side and one side will be left open. The only one that makes a square that fits the shapes is “D”

  42. Eric says:

    I believe that part of this exercise was the misleading nature of the question. One is challenged to look beyond the bounds of the question. I put much more effort into visualizing and manipulating the two shapes because they both seemed to -and do- work.

  43. Tyler says:

    Thanks for the test!

  44. zeynep evin says:

    the answer is definitly d

  45. allstar says:

    c but also d?

  46. D. says:

    Patterns on C and D seems to be correct. However, sizes of every face of the box on the options given here doens’t seem to match the actual proportions shown on the box we have as an example.
    As well as John, my doubt is if this is supossed to be a square.
    Unless the definition of my monitor is wrong, I can’t see any of this options is correct. We can fold boxes, but not exactly the same as the expample that was given.
    Can someone reply which is the correct one?
