Octagon
eight * * * * * A triangular pyramid has six edges: three edges that form the triangular base and then three more edges going up from each vertex of the base to the apex (peak) of the pyramid.
The difference in a triangular and rectangular pyramid only has to do with the base of the pyramid, which in turn decide how many sides the pyramid will have. A triangular pyramid has a base shaped like a triangle, which ends up having a total of 4 sides (including the base itself). A rectangular pyramid has a rectangular base, which ends up having a total of 5 sides (including the base itself).
A triangular pyramid consists of a triangular base. Attached to each side of the triangular base is a triangular face and these all meet up at the apex of the pyramid. There are, therefore, 6 edges, 4 bases and 4 vertices.
Two equilateral triangles or one rhombus.
The volume of any prism can be found by calculating the area of the base and multiplying it by the height of the prism. Recall that a prism is a solid shape composed of a base that is a polygon. By translating that base "up" and adding the "sides" to create the solid shape, you have constructed the prism. And now you can calculate its volume.Note that the base could be triangular, or could be a square, a pentagon, hexagon, or any other polygon. Standard rules apply for calculating the areas of these polygons.

I think it's 3 triangles and 1 rectangle but, I'm only in 6th grade.

if you can visualize the pyrimads of Egypt do so. these pyrimads are square pyrimads. it means they have a square base. a triangular pyrimad has a triangle base with the three corners of the triangle rising up and meeting at one point.
It's an Octohedron, which has 8 triangular faces. Think of one of the great pyramids in Egypt, with a square base and four triangular sides. Take two of these, turn one upside down, and glue them together along the square base. You wind up with 8 triangular faces, and 12 edges!
The shape is a triangular prism. This is a 3-dimensional polygon with two ends that are triangles and three rectangular sides connecting them.* * * * *FYI, a 3-dimensional polygon is known as a polyhedron.
A polygon with n sides, and n triangles, where n ≥ 3. Most commonly, the polygon at the base is a triangle or a square. If the base polygon is regular and the pyramid is a right pyramid (ie apex above the centre of the basal polygon), the triangles will be isosceles.
There are an infinite number of such polyhedra. Starting with a tetrahedron (triangular base), the next up is the quadrilateral pyramid (quadrilateral base), then the pentagonal pyramid, the hexagonal pyramid and so on.
