The given figure has 12 edges, 6 vertices, and 8 faces. This can be obtained by understanding what edges, vertices and faces are and counting them.
What are edges, vertices and faces?
- Edge: A line segment on the boundary and is known as side of a polygon.
- Vertex (plural: vertices): A point where two line segments meet forming an angle.
- Face: A flat surface of a solid.
- For example, a cube has 12 edges, 8 vertices and 6 faces.
In the given figure we can count the edges, vertices and faces.
It is observed that there are 12 edges, 6 vertices, and 8 faces.
Hence the given figure has 12 edges, 6 vertices, and 8 faces. The correct answer is A.
