These are some of a large number of possible answers:
A heptagonal pyramid.
A hexagonal dipyramid.
A pentagonal pyramid, with, on the other side a pentagonal tent-shape - two apices (apexes) instead of one.
A quadrilateral prism, (including cube, cuboid, parallelepiped, rhombohedron).

Yes, it certainly is!
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
it is a 3D shape with 8 faces 8 edges and 6 vertices if you want a picture of it type in pcures of 3D diamonds.
It is a square based pyramid that has 5 faces, 8 edges and 5 vertices
