Let’s go step by step for each shape.
---
First Shape: Cone
-
Name of shape: Cone
(It has a circular base and comes to a point at the top.)
-
Faces: A cone has 2 faces — one flat circular base, and one curved surface that wraps around to the point.
→ So, Faces =
2
-
Edges: An edge is where two faces meet. The only place this happens on a cone is around the circle at the bottom — where the curved face meets the flat base.
→ So, Edges =
1
-
Vertices: A vertex is a corner or point. The tip (top point) of the cone is a vertex.
→ So, Vertices =
1
✔ Check: Yes, standard properties of a cone are 2 faces, 1 edge, 1 vertex.

Second Shape: Cylinder
-
Name of shape: Cylinder
(It has two flat circular ends and a curved side.)
-
Faces: Two flat circles (top and bottom) + one curved surface = 3 faces total.
→ So, Faces =
3
-
Edges: Each circle has an edge where it meets the curved surface. That’s 2 edges — one on top, one on bottom.
→ So, Edges =
2
-
Vertices: A cylinder has no corners or points — everything is smooth or round.
→ So, Vertices =
0
✔ Check: Standard cylinder properties: 3 faces, 2 edges, 0 vertices.
---
Third Shape: Sphere
-
Name of shape: Sphere
(Perfectly round ball — like a basketball or globe.)
-
Faces: A sphere has just one continuous curved surface. No flat parts.
→ So, Faces =
1
-
Edges: There are no lines where faces meet — because there’s only one face.
→ So, Edges =
0
-
Vertices: No corners or points anywhere.
→ So, Vertices =
0
✔ Check: Standard sphere properties: 1 face, 0 edges, 0 vertices.

Final Answer:
Cone
Faces: 2
Edges: 1
Vertices: 1
Cylinder
Faces: 3
Edges: 2
Vertices: 0
Sphere
Faces: 1
Edges: 0
Vertices: 0
