Let’s solve this step by step.
We are looking at three 3D shapes: Cube, Pyramid (square-based), and Rectangular Prism. For each, we need to count:
-
Faces – flat surfaces
-
Edges – where two faces meet (lines)
-
Vertices – corners (points)
---
1. CUBE
A cube is like a box with all sides equal.
-
Faces: Top, bottom, front, back, left, right → that’s
6
-
Edges: Each face has 4 edges, but they’re shared. Think of it as 12 lines total →
12
-
Vertices: Corners — top has 4, bottom has 4 →
8
✔ Cube: Faces = 6, Edges = 12, Vertices = 8
---
2. PYRAMID (Square Base)
This pyramid has a square base and 4 triangular sides meeting at the top point.
-
Faces: 1 square base + 4 triangles =
5
-
Edges: Base has 4 edges, and from each corner of the base up to the top point = 4 more → 4 + 4 =
8
-
Vertices: 4 on the base + 1 on top =
5
✔ Pyramid: Faces = 5, Edges = 8, Vertices = 5
---
3. RECTANGULAR PRISM
Like a shoebox — longer than wide, but still 6 rectangular faces.
-
Faces: Same as cube — top, bottom, front, back, left, right →
6
-
Edges: Also same structure — 12 edges
-
Vertices: 8 corners — just like cube
✔ Rectangular Prism: Faces = 6, Edges = 12, Vertices = 8
---
Final Answer:
Cube:
Faces: 6
Edges: 12
Vertices: 8
Pyramid:
Faces: 5
Edges: 8
Vertices: 5
Rectangular Prism:
Faces: 6
Edges: 12
Vertices: 8
