1. **Is the object square in shape?**
   - **Answer:** No
   - **Reasoning:** The images show that the object has a square face on the top, but the overall shape of the object is not a square. It is a three-dimensional object with a square face and other rectangular faces, forming a prism-like shape.

2. **Has the square been extruded extensively?**
   - **Answer:** Yes
   - **Reasoning:** The images depict that the square face at the top of the object has been extruded downwards to form a taller, three-dimensional shape. This indicates that the square has been extruded to create additional volume and depth, resulting in a prism-like structure.

3. **Does the object maintain its square shape after extrusion?**
   - **Answer:** No
   - **Reasoning:** After the extrusion, the object does not maintain a square shape throughout. While it starts with a square face on the top, the extrusion results in a shape that has rectangular sides, thus changing the overall geometry from a simple square to a more complex prism-like form.
