An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.
a rectangular based pyramid has got 6 edges and four faces and four vertices.
2 faces 1 edge
12 faces * * * * * Correct as far as it goes, but incomplete. 20 vertices 30 edges

How many faces of cuboid
An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.
a rectangular based pyramid has got 6 edges and four faces and four vertices.
I don't think it has any because that's just like asking how many edges has a circle got. (Y)
Pentagonal (not pentaginal). 7 faces 15 edges 10 vertices
2 faces 1 edge
12 faces * * * * * Correct as far as it goes, but incomplete. 20 vertices 30 edges
