A shape that has 8 triangular faces is a octahedron.If you want to see a picture of a octrahedron here is a website.http://en.wikipedia.org/wiki/File:Octahedron.svgI had this as a maths question it was hard.
It is an octahedron which is one of the Platonic Solids having 8 equilateral triangular faces and 12 edges.

A shape that has fewer than 8 faces and fewer than 10 edges is a triangular prism. A triangular prism has 5 faces (2 triangular faces and 3 rectangular faces) and 9 edges. It meets the criteria of having fewer than 8 faces and fewer than 10 edges.
An octahedron: two quadrilateral based pyramids with their bases together.
Your shape is a triangular octagon. * * * * * What on earth is that shape? The most likely answer is an octogonal pyramid.

A Hexahedron has no triangular faces. A Tetrahedron has 4 triangular faces. A octahedron has 8 triangular faces. A Icosahedron has 20 triangular faces. By:-Cherrylvr- :)
A tetrahedral prism is a three-dimensional geometric shape that has two congruent triangular bases and four congruent lateral faces that are in the shape of triangles. The lateral faces connect the corresponding vertices of the two triangular bases, forming a solid with six faces, eight edges, and four vertices.
