An octahedron has eight faces. If it has 62 faces then it is not an octahedron!

What polyhedron has eight sides and all of the are equilateral triangle?
A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
yes
A regular octahedron is a Platonic solid with equilateral triangles for each of the faces. A heptagonal pyramid is an octahedron with one heptagon (a seven sided figure) as its base and 7 triangles, one attached to each side, meeting at the either vertex.
that's easy its a triangle * * * * * That is such a nonsensical answer! A triangle is not even a polyhedron. The correct answer is an octahedron - two square based pyramids stuck together along their bases.
Not necessarily. A heptagon-based pyramid is an octahedron and it has no parallel faces.
