1. **Is the object rectangular in shape?**
   - **Answer:** Yes
   - **Reasoning:** From all three images, the object appears to have four sides with opposite sides being parallel and four right angles, which defines a rectangle.

2. **Is the object large in size?**
   - **Answer:** Unclear
   - **Reasoning:** The images do not provide any reference for scale or size comparison, so it is not possible to determine the actual size of the object.

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