Problem Overview:
The task is to identify the 3D shapes shown in the images and determine the number of faces each shape has. The shapes are provided in a grid, and there is a list of possible names for the shapes at the bottom of the worksheet.
Solution:
#### Step 1: Identify Each Shape
We will analyze each shape one by one and determine its name and the number of faces.

Row 1:
1.
Shape 1 (Top Left):
-
Description: This shape has a triangular base and three triangular sides.
-
Name: Triangular pyramid (or tetrahedron).
-
Number of Faces: A triangular pyramid has 4 faces (1 triangular base + 3 triangular sides).
2.
Shape 2 (Top Middle):
-
Description: This shape has six square faces.
-
Name: Cube.
-
Number of Faces: A cube has 6 faces.
3.
Shape 3 (Top Right):
-
Description: This shape has two circular bases and a curved surface.
-
Name: Cylinder.
-
Number of Faces: A cylinder has 3 faces (2 circular bases + 1 curved surface).

Row 2:
4.
Shape 4 (Bottom Left):
-
Description: This shape has two square bases and four rectangular sides.
-
Name: Cuboid.
-
Number of Faces: A cuboid has 6 faces (2 square bases + 4 rectangular sides).
5.
Shape 5 (Bottom Middle):
-
Description: This shape has a triangular base and three rectangular sides.
-
Name: Triangular prism.
-
Number of Faces: A triangular prism has 5 faces (2 triangular bases + 3 rectangular sides).
6.
Shape 6 (Bottom Right):
-
Description: This shape has a square base and four triangular sides.
-
Name: Square-based pyramid.
-
Number of Faces: A square-based pyramid has 5 faces (1 square base + 4 triangular sides).

#### Step 2: Fill in the Table
Now, we can fill in the table with the names and number of faces for each shape.
| Shape Image | Name of Shape | Faces |
|-------------|------------------------|-------|
| Shape 1 | Triangular pyramid | 4 |
| Shape 2 | Cube | 6 |
| Shape 3 | Cylinder | 3 |
| Shape 4 | Cuboid | 6 |
| Shape 5 | Triangular prism | 5 |
| Shape 6 | Square-based pyramid | 5 |

#### Final Answer:
\[
\boxed{
\begin{array}{|c|c|c|}
\hline
\text{Shape Image} & \text{Name of Shape} & \text{Faces} \\
\hline
\text{Shape 1} & \text{Triangular pyramid} & 4 \\
\hline
\text{Shape 2} & \text{Cube} & 6 \\
\hline
\text{Shape 3} & \text{Cylinder} & 3 \\
\hline
\text{Shape 4} & \text{Cuboid} & 6 \\
\hline
\text{Shape 5} & \text{Triangular prism} & 5 \\
\hline
\text{Shape 6} & \text{Square-based pyramid} & 5 \\
\hline
\end{array}
}
