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

   hmmm… sory, but C and D are equal…

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

   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.

    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.

    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.

    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?

    
    
    
17. Alvaro on December 21, 2007 at 5:26

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

    c and d

    
    
    
19. Mitch on January 4, 2008 at 5:12

    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.

    
    
    
20. Mark on January 6, 2008 at 8:17

22. manash on January 12, 2008 at 7:57

    BOTH ‘D’ AND ‘C’ARE CORRECT

25. mackkk on February 22, 2008 at 5:11
