C & D
Thanks, mackkk. It is only D.
It’s D, not too hard :)
it’s D, this one wasn’t hard
it is C only the correct one
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?
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.
C and D are correct.
You have to rotate C in three dimensions for it to fit but it does ;)
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
C and D
=)
C & D
D only if you’re not supposed to flip it, both C and D if you’re allowed to flip it.
D. C doesnt worklk because the triangle would be on the side, not the top.…
It’s D. Can’t be C, just look at the parallel lines. They aren’t 90^ to the circle.
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.
I’m pretty sure that C and D are both applicable.☺
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.
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”
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.
Thanks for the test!
D
the answer is definitly d
c but also d?
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?
C and D are correct but the image is stretched. If you open the image in another browser window it will appear correctly, as a cube. That is the confusing part.
