A triangular prism has 9 edges.
a rectangular based pyramid has got 6 edges and four faces and four vertices.
12 faces * * * * * Correct as far as it goes, but incomplete. 20 vertices 30 edges
a hexagon has one face and 6 edges a hexagonal pyramid has 7 faces a hexagonal prism has 8 faces
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. This formula calculates the total area of all six faces of the rectangular prism. It is derived from the formula for the surface area of a box, which consists of three pairs of identical rectangular faces.

Yep, you got it!
A triangular prism has 9 edges.

Pentagonal (not pentaginal). 7 faces 15 edges 10 vertices
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.

Well, honey, that sounds like a hexagonal prism to me. It's got those six faces, six vertices, and ten edges, making it the life of the 3D shape party. So, go ahead and strut your stuff with that hexagonal prism knowledge!
8(top)+8(bottom)+8(sides)=24 24 edges(sides)
Triangular prism
Heptagonal prism * * * * * No, a heptagonal prism has 9 faces. The correct answer is a hexagonal pyramid.
