Final Answer:
The table contains errors. Correct values are:
- Cylinder: 3 faces, 0 vertices, 2 edges → should be 3 faces, 0 vertices, 0 edges (or 2 edges if counting curved edge as 1, but typically 0 for elementary level).
- Cone: 2 faces, 1 vertex, 1 edge → should be 2 faces, 1 vertex, 0 or 1 edge (typically 0 for elementary level).
- Sphere: 1 face, 0 vertices, 0 edges → should be 0 faces, 0 vertices, 0 edges.
- Triangular Pyramid: 4 faces, 4 vertices, 6 edges → correct.
- Square Pyramid: 5 faces, 5 vertices, 8 edges → should be 5 faces, 5 vertices, 8 edges — this is actually correct.
But since the task likely expects standard elementary answers:
Corrected Table:
- Cylinder: Faces=3, Vertices=0, Edges=0
- Cone: Faces=2, Vertices=1, Edges=0
- Sphere: Faces=0, Vertices=0, Edges=0
- Triangular Pyramid: Faces=4, Vertices=4, Edges=6 → correct
- Square Pyramid: Faces=5, Vertices=5, Edges=8 → correct
So the only real error is in Sphere and possibly Cylinder/Cone edges.
But based on common grade 7 curriculum:
Final corrected answer for missing/incorrect parts:
Cylinder: Edges = 0
Cone: Edges = 0
Sphere: Faces = 0, Edges = 0
Triangular Pyramid: All correct
Square Pyramid: All correct
→ So the corrected numbers to fill in or fix are:
Cylinder – Edges: 0
Cone – Edges: 0
Sphere – Faces: 0, Edges: 0
But since the user just wants the final answer and didn’t ask for explanation or teaching, here’s the clean final answer:
Final Answer:
Cylinder: 3 faces, 0 vertices, 0 edges
Cone: 2 faces, 1 vertex, 0 edges
Sphere: 0 faces, 0 vertices, 0 edges
Triangular Pyramid: 4 faces, 4 vertices, 6 edges (correct)
Square Pyramid: 5 faces, 5 vertices, 8 edges (correct)
