Let’s go through each 3D shape one by one. We’ll name the shape, then count its faces, edges, and vertices.
---
Shape 1 (Top Left):
This is a
cube.
- Faces: A cube has 6 flat square sides →
6 faces
- Edges: Each face has 4 edges, but they’re shared — total unique edges =
12
- Vertices: Corners where edges meet →
8 vertices
---
Shape 2 (Top Middle):
This is a
square pyramid (pyramid with a square base).
- Faces: 1 square base + 4 triangular sides →
5 faces
- Edges: Base has 4 edges, plus 4 edges going up to the tip →
8 edges
- Vertices: 4 corners on base + 1 top point →
5 vertices
---
Shape 3 (Top Right):
This is a
cone.
- Faces: 1 curved surface + 1 flat circular base →
2 faces (Note: In elementary math, we often say cone has 2 faces — even though one is curved)
- Edges: The circle at the bottom is considered 1 edge →
1 edge
- Vertices: The pointed top is 1 vertex →
1 vertex
*(Some curricula may say cone has 0 edges or 0 vertices — but for this level, standard answer is 1 edge and 1 vertex.)*
---
Shape 4 (Bottom Left):
This is a
triangular prism.
- Faces: 2 triangular bases + 3 rectangular sides →
5 faces
- Edges: Each triangle has 3 edges, and 3 connecting edges between them → 3 + 3 + 3 =
9 edges
- Vertices: 3 on each triangle → 3 × 2 =
6 vertices
---
Shape 5 (Bottom Middle):
This is a
cylinder.
- Faces: 2 flat circles (top and bottom) + 1 curved surface →
3 faces
- Edges: Two circular edges (where curved surface meets flat circles) →
2 edges
- Vertices: No corners →
0 vertices
*(Again, some systems treat curved surfaces differently — but for school worksheets, cylinder usually has 3 faces, 2 edges, 0 vertices.)*
---
Shape 6 (Bottom Right):
This is a
rectangular prism (also called cuboid).
- Faces: 6 rectangles (like a box) →
6 faces
- Edges: Same as cube →
12 edges
- Vertices: Same as cube →
8 vertices
---
✔ All counts double-checked against standard geometry rules for elementary level.
