1. The problem describes a shape made by attaching 6 "V" letters together to form a star-like shape. 2. Each "V" letter has 2 corners (the points where the lines meet), so 6 "V" letters have $6 \times 2 = 12$ corners in total if they do not share corners. 3. Since the "V" letters are attached together to form a star shape, some corners may overlap. 4. However, the problem gives possible answers as 6, 10, 13, and 12. Among these, 12 matches the total corners if counted all individually. 5. Therefore, the star shape formed by attaching 6 "V" letters has 12 corners. Answer: 12
