A regular tetrahedron (triangular pyramid).
3d shape Well actually it is a Cube
A 3D shape with all triangular faces can be a tetrahedron pyramid.
a triangular prism easy
A prism.
The 3d shape that have five faces would be a triangular prism **************** or a pyramid
There are several of these. For example, dice.See related link below for more shapes
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
CUBOID
The 3-D shape that has 4 faces is the tetrahedron. All of its faces are triangular, and they all converge at a single vertex.
A cube satisfies that description.
A 3d shape with 5 faces can be a square pyramid
a sphere
