To design a polygonal mesh representing a rectangular solid, follow these steps:

Step 1/4:

Start by determining the dimensions of the rectangular solid, denoting the length as L, the width as W, and the height as H.

Step 2/4:

Next, define the vertices of the rectangular solid using the rectangular coordinate system. There will be a total of 8 vertices:

Next, define the vertices of the rectangular solid using the rectangular coordinate system. There will be a total of 8 vertices:

- Vertex 1: (0, 0, 0)
- Vertex 2: (L, 0, 0)
- Vertex 3: (L, W, 0)
- Vertex 4: (0, W, 0)
- Vertex 5: (0, 0, H)
- Vertex 6: (L, 0, H)
- Vertex 7: (L, W, H)
- Vertex 8: (0, W, H)

Step 3/4:

Connect the vertices to form the edges of the rectangular solid. There will be a total of 12 edges:

Connect the vertices to form the edges of the rectangular solid. There will be a total of 12 edges:

- Edge 1: Vertex 1 to Vertex 2
- Edge 2: Vertex 2 to Vertex 3
- Edge 3: Vertex 3 to Vertex 4
- Edge 4: Vertex 4 to Vertex 1
- Edge 5: Vertex 5 to Vertex 6
- Edge 6: Vertex 6 to Vertex 7
- Edge 7: Vertex 7 to Vertex 8
- Edge 8: Vertex 8 to Vertex 5
- Edge 9: Vertex 1 to Vertex 5
- Edge 10: Vertex 2 to Vertex 6
- Edge 11: Vertex 3 to Vertex 7
- Edge 12: Vertex 4 to Vertex 8

Step 4/4:

Finally, connect the edges to form the faces of the rectangular solid. There will be a total of 6 faces:

Finally, connect the edges to form the faces of the rectangular solid. There will be a total of 6 faces:

- Face 1: Bottom face (formed by edges 1, 2, 3, and 4)
- Face 2: Top face (formed by edges 5, 6, 7, and 8)
- Face 3: Front face (formed by edges 1, 10, 11, and 9)
- Face 4: Right face (formed by edges 2, 10, 12, and 3)
- Face 5: Back face (formed by edges 3, 11, 12, and 4)
- Face 6: Left face (formed by edges 4, 9, 8, and 7)
