This question is not the clearest. However, an n-sided prism will typically have n+2 faces: the n sides, and the two ends. So a nine-sided prism will have 11 faces.
A prism has two polygonal faces at each end and these may have any number of sides, n. The prism also has n rectangular faces.
A heptagonal prism is a prism with a heptagon (7-sided polygon) as its base. It has 14 faces (2 heptagons and 12 rectangles), 20 vertices (2 at each corner of the heptagon and 2 at each corner of the rectangles), and 28 edges (7 edges on each heptagon base and 12 edges around the sides connecting the corresponding vertices of the base and top heptagon).
I think you mean *Pentagonal Prism" ;D Anyway, there are two Pentagons at each end of the prism, so, so far you have two faces. Now, since a pentagon has 5 sides, there will be 5 faces. 5 + 2 = 7 A Pentagonal Prism has 7 faces.
A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
A hexagonal prism has a total of 12 sides. It consists of two hexagonal bases, each with 6 sides, and 6 rectangular lateral faces connecting the corresponding sides of the hexagons. Therefore, the total is 6 (from one hexagon) + 6 (from the other hexagon) + 6 (from the lateral faces) = 12 sides.
Oh, what a happy little question! The number of faces on a prism is always two more than the number of sides on its base. You see, the base of the prism creates one face on the bottom and another face on the top, and each side of the base connects to one face on the side of the prism. Just like painting a beautiful landscape, it's all about seeing how each part comes together to create a lovely whole.

The number of faces in a prism is one face for each of the sides of its cross-section plus the two end faces. A quadrilateral prism has a quadrilateral as its cross-section. Therefore it has 4 + 2 = 6 faces.
For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.
An octagonal prism is a solid which has 8 faces with each face having 8 sides, and 2 Bases.
A prism has 2n vertices, where n is the number of sides in its base polygon. This is because each side of the base polygon is connected to another side by a vertical edge, and each vertex is formed at the intersection of two edges. So, a prism with a pentagonal base would have 10 vertices (5 vertices from the base polygon and 5 vertices from the top polygon).
5- each of the sides and the base.

All prisms have a face on each end. Additionally, they will have a number of faces corresponding to the number of sides on the polygon that is on an end. For a triangular prism, that's 2 + 3 = 5 faces. For a square prism, that's 2 + 4 = 6 faces. For your pentagon prism, that's 2 + 5 = 7 faces.

A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
