To solve the problem, we need to identify each 3D shape and determine the number of faces, edges, and vertices for each. Let's go through each shape step by step:
---
1. First Shape: Cube
-
Name: Cube
-
Faces: A cube has 6 square faces.
-
Edges: A cube has 12 edges.
-
Vertices: A cube has 8 vertices.
Answer:
- Name: Cube
- Faces: 6
- Edges: 12
- Vertices: 8
---
2. Second Shape: Triangular Pyramid (Tetrahedron)
-
Name: Triangular Pyramid (or Tetrahedron)
-
Faces: A triangular pyramid has 4 triangular faces.
-
Edges: A triangular pyramid has 6 edges.
-
Vertices: A triangular pyramid has 4 vertices.
Answer:
- Name: Triangular Pyramid (Tetrahedron)
- Faces: 4
- Edges: 6
- Vertices: 4
---
3. Third Shape: Cone
-
Name: Cone
-
Faces: A cone has 2 faces – one curved surface and one circular base.
-
Edges: A cone has 1 edge (the circular edge of the base).
-
Vertices: A cone has 1 vertex (the tip).
Answer:
- Name: Cone
- Faces: 2
- Edges: 1
- Vertices: 1

4. Fourth Shape: Rectangular Prism (Cuboid)
-
Name: Rectangular Prism (or Cuboid)
-
Faces: A rectangular prism has 6 faces (all rectangles).
-
Edges: A rectangular prism has 12 edges.
-
Vertices: A rectangular prism has 8 vertices.
Answer:
- Name: Rectangular Prism (Cuboid)
- Faces: 6
- Edges: 12
- Vertices: 8
---
5. Fifth Shape: Sphere
-
Name: Sphere
-
Faces: A sphere has 0 faces (it is a perfectly round surface with no flat surfaces).
-
Edges: A sphere has 0 edges.
-
Vertices: A sphere has 0 vertices.
Answer:
- Name: Sphere
- Faces: 0
- Edges: 0
- Vertices: 0

Final Answer
Here is the completed table:
| Shape Image | Name | Faces | Edges | Vertices |
|-------------|---------------|-------|-------|----------|
| Cube | Cube | 6 | 12 | 8 |
| Tetrahedron | Triangular Pyramid | 4 | 6 | 4 |
| Cone | Cone | 2 | 1 | 1 |
| Cuboid | Rectangular Prism | 6 | 12 | 8 |
| Sphere | Sphere | 0 | 0 | 0 |
Boxed Final Answer:
\[
\boxed{
\begin{array}{|c|c|c|c|c|}
\hline
\text{Shape Image} & \text{Name} & \text{Faces} & \text{Edges} & \text{Vertices} \\
\hline
\text{Cube} & \text{Cube} & 6 & 12 & 8 \\
\hline
\text{Tetrahedron} & \text{Triangular Pyramid} & 4 & 6 & 4 \\
\hline
\text{Cone} & \text{Cone} & 2 & 1 & 1 \\
\hline
\text{Cuboid} & \text{Rectangular Prism} & 6 & 12 & 8 \\
\hline
\text{Sphere} & \text{Sphere} & 0 & 0 & 0 \\
\hline
\end{array}
}
