The correct attributes of a three-dimensional right rectangular prism are: It has 8 vertices, 6 faces, and 12 edges.
To break it down:
- Vertices: A rectangular prism has 8 corners (vertices).
- Faces: It has 6 rectangular faces (top, bottom, and the four sides).
- Edges: There are 12 edges in total (4 edges for each pair of opposite faces).
Therefore, the correct response is: It has 8 vertices, 6 faces, and 12 edges.
