1. **Is the object rectangular in shape?**
   - **Answer:** Yes
   - **Reasoning:** From all three images, the object clearly has four straight edges and right angles at each corner, which defines a rectangular shape.

2. **Is the object large in size?**
   - **Answer:** Unclear
   - **Reasoning:** The images do not provide any reference for scale or context that indicates the actual size of the object. Without such information, it is not possible to determine if the object is large.

3. **Is the object marginally extruded?**
   - **Answer:** Yes
   - **Reasoning:** The images show that the object has a noticeable thickness, indicating that it is not merely a flat plane but has some depth, which suggests it is extruded to some extent.
