The correct attributes of a three-dimensional right rectangular prism are:
- Vertices: 8
- Faces: 6
- Edges: 12
Thus, the first option is correct: It has 8 vertices, 6 faces, and 12 edges.
To elaborate further:
- Vertices are the points where the edges meet.
- Faces are the flat surfaces that make up the boundaries of the prism.
- Edges are the line segments where two faces meet.
In summary, a right rectangular prism is defined by these specific attributes.
