A pentagonal prism has seven faces.
Here's a breakdown:
- Two pentagonal faces: These are the bases of the prism, forming the top and bottom.
- Five rectangular faces: These connect the two pentagonal bases, forming the sides of the prism.
Think of it like a box with a pentagon as its base. The top and bottom are the pentagonal faces, and the sides are the rectangular faces.
You can visualize this by imagining a regular pentagon (a five-sided shape with all sides and angles equal) and then extending lines perpendicular to each side, forming a rectangular "wall." Connect these walls at the top to create the other pentagonal face.
