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.

2. santosh says:

3. bms says:

D alt. for sure.

4. ilana says:

D

5. Susie says:

I understand the confusion between C & D. I first said both C & D. Then, I realized that I was assuming it was a cube. However, the image shows up as a rectangluar prism on my screen. If that is the case, then only C would be correct. Thanks for letting us know that it is supposed to be a cube.

6. Susie says:

Oops, excuse the next to last senctnece in my comment above. I meant that “If that is the case, then only C would be correct.”

7. Susie says:

Well, I’m definitely having difficult with my memory or my fingers tonight! The comment above should read that If that’s the case only D, yes D, would be correct. I need sleep!

8. Farhan says:

9. Linda says:

D only C has the red triangle fit into the puzzle going the wrong direction.

10. Helen says:

11. Maria says:

I honestly believe its B if you REALLY think about folding the box that way.

13. Charles says:
