cube, cuboid, trapezoid prism
An octahedron is a polyhedron with eight faces, twelve edges, and six vertices
Hexagonal prism
then it's a - Dodecahedron
a twelve sided shape with 12 faces, 30 edges and 20 vertices.
A hexagonal prism.
It depends on the exact shape. An octahedron is a shape with eight faces. It can be a heptagonal pyramid (8 vertices, 14 edges), or a hexagonal prism (12 vertices, 18 edges), square dipyramid (6 vertices, 12 edges) are some examples. There are more.
A quadrilateral based pyramid.
A shape with six rectangular sides is known as a rectangular prism, also referred to as a cuboid. Each of its six faces is a rectangle, and it has opposite faces that are congruent. This three-dimensional shape has eight vertices and twelve edges.
A sphere has no faces, edges, or vertices.
There is no limit to the number of vertices nor edges.
A square prism would be oblong in shape, ie a cuboid.
An octahedron has 6 vertices. It is a polyhedron with eight triangular faces, and its vertices are the points where the edges meet. Each vertex is connected to four other vertices, forming a symmetrical shape.
