Step-by-step solution for: What Are 3D Shapes? Explained for Elementary School
It looks like you've uploaded a chart titled "3D Shapes" that lists various three-dimensional geometric shapes along with their properties: Faces, Edges, and Vertices. However, there are some inaccuracies in the table, particularly in the Edges and Vertices columns for certain shapes.
Let’s go through each shape and correct any errors, then explain the reasoning behind the correct values.
---
#### 1. Sphere
- Diagram: Orange sphere
- Faces: 1 curved surface ✔
- Edges: 0 ✔ (No edges — smooth surface)
- Vertices: 0 ✔ (No corners)
✔ Correct
---
#### 2. Hemisphere
- Diagram: Pink half-sphere
- Faces: 1 flat face + 1 curved surface ✔
- Edges: 1 ✔ (The circular edge where the flat face meets the curve)
- Vertices: 0 ✔ (No corners)
✔ Correct
---
#### 3. Cone

✔ Correct
---
#### 4. Tetrahedron (Triangular-based pyramid)
- Diagram: Blue triangular pyramid

- Face: A flat or curved surface.
- Edge: Where two faces meet (line segment).
- Vertex: A corner point where edges meet.
For prisms, the formula is:
- Faces = 2 (bases) + number of sides of base
- Edges = 3 × number of sides of base
- Vertices = 2 × number of sides of base
For pyramids:
- Faces = 1 (base) + number of sides of base
- Edges = 2 × number of sides of base
- Vertices = 1 (apex) + number of sides of base
