A pyramid with 18 edges would be called a nonagonal pyramid. A prism with 18 edges is called a hexagonal prism.
They are all polyhedra with 12 edges.
Heptagonal prism * * * * * No, a heptagonal prism has 9 faces. The correct answer is a hexagonal pyramid.
It could be a pentagonal pyramid, but there are other possible shapes.
A hexagonal prism has eighteen edges. Hexagonal prisms also have twelve vertices and eight faces, including two hexagonal bases and six rectangular faces.
Five faced pyramid have 10 edges.Above is the answer for a pentagonal prism it has six faces (the bottom is also a face with five of the edges)A rectangular pyramid with five faces (four triangles and one rectangle) has eight edges.
triangular pyramid

A square pyramid. * * * * * A square pyramid has eight edges so, NO, it is not a square pyramid. It could be a triangular prism, though.
for any prism , number of ___ + number of vertices = number of edges + ___
A hexagonal prism has 12 vertices, 8 faces and 18 edges. A hexagonal pyramid has 7 vertices, 7 faces and 12 edges.
A hexagonal prism.
A tetrahedron is a triangular based pyramid that has no parallel edges whereas most prisms have parallel edges such as a cuboid or a cylinder.
A sphere does NOT have any edges
