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
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.
a hexagon has one face and 6 edges a hexagonal pyramid has 7 faces a hexagonal prism has 8 faces
Yep, you got it!

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.
