SPATIAL REASONING DIAGNOSTIC

Question 2: The Unfolding Cube

Instructions: You should spend approximately 15-20 minutes on this question. Read both parts carefully before answering.

Part B: Written Explanation (Questions 2.2)

2.2 In the space provided, please describe your step-by-step thought process for determining the correct answer to Question 2.1. Your explanation should be clear, coherent, and well-organised, demonstrating your ability to articulate complex spatial reasoning. Consider the following points in your response:

• Did you focus on which faces must touch? If so, how?
• Did you identify opposite faces to eliminate options? Explain how this helped.
• Did you mentally "anchor" one face and fold the others around it? Describe your visualization process.

Your goal is to make your reasoning transparent to a reader, much like explaining a design concept. Aim for at least 150 words.
