Spatial Reasoning: Cube Folding, Paper Cutting, and Folds

Learn core concepts, essential formulas, and attempt practice questions designed on the latest TCS NQT testing patterns.

Key Concepts & Formulas

1Opposite faces rule: in open cubes, alternate faces (separated by one block) are opposite.
2Opposite faces can never be adjacent or visible together on a folded cube.

Practice Question 1

In an open net, face 1 is alternate to face 3. Can they be adjacent in the folded cube?

A) No, never

B) Yes, always

C) Only sometimes

D) Depends on other faces

Correct Answer: A) No, never

Step-by-step Solution: Alternate faces in an unfolded net become opposite faces when folded. Opposite faces can never share an edge or be adjacent.

Practice Question 2

A paper is folded in half, a circle is cut in the center. When opened, how many holes are there?

A) 2

B) 1

C) 4

D) 0

Correct Answer: A) 2

Step-by-step Solution: Since the paper was folded once (2 layers), cutting 1 hole through the layers results in 2 holes when unfolded.

Identify opposite face pairs in open nets first to eliminate invalid cube options.
