Pyramid, but to be exact it would be a Triangular Pyramid ;) * * * * * To be exact ... but WRONG! A triangular pyramid has 4 faces and 4 vertices! A shape with 5 faces and vertices is a quadrilateral based pyramid - of which a special case would be a square based pyramid.
A pyramid will have as many triangular faces as the number of sides its base has, plus one in the shape of its base. This means an octagon based pyramid has nine faces (eight triangular ones plus the octagon base).
