Let’s go through each shape one by one and figure out:
1. The name of the shape
2. How many faces it has
3. How many edges it has
4. How many vertices (corners) it has
---
First Shape:
- It’s round on the bottom and comes to a point on top → that’s a
cone.
- Faces: A cone has 1 flat face (the circular base) and 1 curved surface. In elementary math, we usually count only the flat faces unless told otherwise — but sometimes both are counted. Let’s check standard curriculum: Most schools say a cone has
2 faces (1 flat + 1 curved).
- Edges: Where two surfaces meet. The cone has 1 edge — where the curved surface meets the base.
- Vertices: A vertex is a corner point. The cone has 1 vertex at the top tip.
✔ So for cone:
- Name: Cone
- Faces: 2
- Edges: 1
- Vertices: 1
---
Second Shape:
- It’s like a can — straight sides, flat top and bottom → that’s a
cylinder.
- Faces: 2 flat faces (top and bottom circles) + 1 curved surface → total
3 faces.
- Edges: Where surfaces meet — top circle meets curved side (1 edge), bottom circle meets curved side (1 edge) →
2 edges.
- Vertices: No corners →
0 vertices.
✔ So for cylinder:
- Name: Cylinder
- Faces: 3
- Edges: 2
- Vertices: 0
---
Third Shape:
- Perfectly round in all directions → that’s a
sphere.
- Faces: No flat surfaces →
0 faces (some might argue 1 curved face, but again, in most school worksheets, they count flat faces only → so 0).
- Edges: No straight lines or boundaries →
0 edges.
- Vertices: No corners →
0 vertices.
✔ So for sphere:
- Name: Sphere
- Faces: 0
- Edges: 0
- Vertices: 0
---
Final Answer:
Cone: Faces: 2, Edges: 1, Vertices: 1
Cylinder: Faces: 3, Edges: 2, Vertices: 0
Sphere: Faces: 0, Edges: 0, Vertices: 0
