Two or zero. A cuboid can have 6 rectangular faces; or 4 rectangular faces with 2 square faces on either end
6 everybody knows that
An octagon doesn't have any faces: faces only apply to 3-dimensional objects. If you meant edges, or sides, an octagon has eight. If you meant an octagonal prism, they have ten faces.
2 faces
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!
A cuboid has 8 vertices, 12 edges and 6 faces
Two or zero. A cuboid can have 6 rectangular faces; or 4 rectangular faces with 2 square faces on either end
6 everybody knows that
An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.
A cube has 6 sides, and so does a cuboid.
a rectangular based pyramid has got 6 edges and four faces and four vertices.
2 faces 1 edge
Pentagonal (not pentaginal). 7 faces 15 edges 10 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
It has 24 edges, so now you can count its number of sides.
A cuboid has got six flat surfaces.
