a heptagonal pyramid has 8 faces
Do pyramids have perpendicular faces ?
cube, cone, sphere * * * * * All wrong. The correct answer is a heptagonal prism.
A heptagonal based pyramid has: 8 faces 8 vertices & 14 edges
It has 9 faces It has 21 edges Its end faces are parallel to each other
It will have 8 faces, 14 edges and 8 vertices
A heptagonal what? Prism, pyramid or something else?

Faces = 8 Edges = 14 Corners = 8
Faces: 14 Vertices: 9 Edges: 21

Assuming a regular decagon is the base of the prism, it would be 10 faces. With an irregular decagon, it is possible that two (or more) of the edges of the decagons are perpendicular, so all 12 faces could have perpendicular edges.
