Understanding the New Polyhedron
When we cut off the corners of a cube, we create a new polyhedron with distinct characteristics. Let’s break down the changes in vertices and faces.
Original Cube Properties
- A cube has **8 vertices**.
- A cube has **6 faces**.
Vertices After Cutting Corners
- Each corner (vertex) of the cube is cut off, which transforms it into a triangular face.
- When we cut off the **8 corners**, each corner creates **1 new vertex**.
- Additionally, the original cube’s **8 vertices** will now be replaced by **new vertices** created by the cuts.
**Total New Vertices Calculation:**
- **Original vertices:** 8 (from the cube)
- **New vertices from cuts:** 8 (one from each corner)
- **Total vertices:** 8 (original) + 8 (new) = **16 vertices**.
Faces After Cutting Corners
- The original **6 square faces** of the cube are transformed into **octagonal faces**. Each square face, when the corners are cut, becomes an octagon.
- The **8 triangular faces** are formed from cutting off each corner of the cube.
**Total Faces Calculation:**
- **Octagonal faces:** 6 (one for each face of the cube)
- **Triangular faces:** 8 (one for each corner cut)
- **Total faces:** 6 (octagons) + 8 (triangles) = **14 faces**.
Final Summary
- **Total Vertices:** 16
- **Total Faces:** 14
This new polyhedron is known as a truncated cube. By understanding the changes in vertices and faces, we can appreciate the structure of this fascinating shape!
