Question

Which of the following finished patterns can be obtained from the piece of cardboard (X) shown below? 

• A. 1
• B. 2
• C. 3
• D. 4
• E. Not any of the above

Hint:

For folding problems:
• Track special markings (like X, dots).
• Visualize which faces become adjacent.
• Eliminate options with missing or misplaced features.

Answer 1

The Correct Option is C

Concept: This is a paper folding / box formation problem:
• A flat cardboard is folded to form a 3D shape.
• Markings (lines, shaded parts) must align correctly after folding.
Step 1: Observe the given cardboard (X).
• Contains diagonal cross lines (X-shape).
• Has a small shaded rectangular part.
• Side flaps are used for folding.

Step 2: Understand folding.
• The central face with cross lines becomes one visible face.
• Side flaps fold inward to form edges.
• Relative positions of markings must remain consistent.

Step 3: Check options.
• Option (1) and (2): Missing cross pattern → incorrect.
• Option (4): Incorrect orientation of shaded part.
• Option (3): Correctly shows:
• Cross lines on visible face
• Proper placement of shaded part
• Correct folding alignment

Step 4: Conclusion. Answer = 3
