CUBOID
The faces of a cube are all the same shape - a square.
A dodecahedron (literally, "12 face solid").The "regular dodecahedron" has 12 identical faces, all regular pentagons ("5 sided flat shape").But there are many, many other 3d shapes with 12 faces, including the rhombic dodecahedron which has 12 identical faces, all 4 sided parallelograms.what shape has 12 faces?
A regular tetrahedron (triangular pyramid).
A Cuba has 6 congruent faces
A 3-d shape, all of whose faces are rhombi, is called a parallelepiped.
3d shape Well actually it is a Cube
Shape
a triangular pyramid.
A cube.
A parellelepiped (pronounced parellel pie ped) is any shape with 6 faces and 12 edges. A cuboid, also called a rectangular parallelepiped, is a parallelepiped of which all faces are rectangular. A cube is a cuboid with square faces. A rhombohedron is a parallelepiped with all rhombic faces. A trigonal trapezohedron is a rhombohedron with congruent rhombic faces. http://commons.wikimedia.org/wiki/File:Parallelepipede.png
A 3D shape with all triangular faces can be a tetrahedron pyramid.
A cube satisfies that description.
