A tetrahedron (4 triangular faces) is the only polyhedron that has a unique configuration of faces, edges and vertices.
For any polyhedron with n (>4) faces, there is a prism with a pair of n-2 sided polygons as bases as well a pyramid whose base is an n-1 sided polygon. There are many other configurations for polyhedra with more faces. For example, there are ten [topologically] different figures with 6 faces: 3 of these are concave polyhedra.

What 3-dimensional figures have the same number of faces?
triangular prism
Write two figures of 3 dimensional figures that have the same number of faces?
A triangular prism and a square pyramid.
Are edges and sides the same thing?
It gets confusing. In a futile attempt to standardize terminology, use "sides" for 2d figures (the sides of a square), use "edges" for 3d figures (the edges of a prism) and use "faces" for 3d figures (the faces of a tetrahedron).
What is the relationship between the coefficient of a number in scientific notation and the number of significant figures?
The number of digits in the coefficient should be exactly the same as the number of significant figures.
Do all pyramids have the same number of faces?
no
Which figures have the same number of faces as vertices?
They are square based pyramids

Does a cuboid have the same number of faces as a cube?
Yes, they both have 6 faces.
Do all pyramids have the same number of faces?
no
Which two pairs of number contain the same significant figures 34500 and 340500?
This pair does not have the same or the same number of significant figures.
How does conversion factors affect the number of significant figures in a problem?
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
What pyramid has 5 faces 9 edges and 6 vertices?
If the number of vertices is not the same as the number of faces, it cannot be a pyramid.
What shape has the same number of vertices as faces?
cone
