The solid figure that has the same number of faces and vertices and has 8 edges is a cube. A cube has 6 faces, 8 vertices, and 12 edges, so it fits the description given.
Any pyramid.
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.
A rectangular dipyramid.
Any polyhedron can be deformed (its angles changed) without affecting the number of edges, vertices or faces.
A triangular based pyramid has 4 faces and 4 vertices
The solid figure that has the same number of faces and vertices and has 8 edges is a cube. A cube has 6 faces, 8 vertices, and 12 edges, so it fits the description given.
Any pyramid.
A cuboid, a parallelepiped.
If the number of vertices is not the same as the number of faces, it cannot be a pyramid.
13 vertices. A pyramid always has the same number of faces and vertices.
cone
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.
Sphere ( 0 faces , 0 edges , 0 vertices )
A rectangular dipyramid.
Any polyhedron can be deformed (its angles changed) without affecting the number of edges, vertices or faces.
They are square based pyramids
