The Answer is isosahedron
Tetrahedron.
An 8-faced 3D shape is called an octahedron. It is a polyhedron with eight triangular faces, 12 edges, and six vertices.
triangular prism
A prism whose ends are 18-gons.
A triangular prism, where the two ends are triangles.
A PRISM is a solid whose side faces are parallelograms and whose ends(or bases ) are congruent parallel rectilinear figures.
It ends up with 88 edges
A prism whose ends are polygons with n sides will have 2n + 2 faces in all.
That shape is called a triangular prism. A prism is made of rectangles arranged in a tube with any 2D shape at the ends. This shape determines what kind of prism it is, you can get pentagonal, hexagonal, and many other types of prism.
A rather simplistic answer is: A cube or cuboid shape has (usually) 2 sides, 2 ends, 1 top and 1 bottom.
A square prism is one whose two ends are square and the remaining 4 faces are rectangles.
