What is the sum of the faces and bases of a triangular pyramid?
Number of faces = 4 Any one of them could be a base, so number of bases also = 4 Therefore, sum = 8
What is the surface area of this triangular pyramid?
It is the sum of the areas of its four faces.
How do you find the surface area of a triangle pyramid?
Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.
When was the surface area formula developed for the triagular prism?
A prism is a polyhedron with two parallel bases bounded by congruent polygons and with lateral faces bounded by parallelograms that connect the corresponding sides of the bases. The height of a prism is any perpendicular line drawn from a point on one base to the other base. If the the bases' shape of a prism is a triangle, we call it a triangular prism (it has 3 faces). The surface area is the sum of the bases' area and the faces' area (lateral area).

What is the formula for the surface area of a rectangular pyramid?
PyramidV = 1/3 bhb is the area of the baseSurface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases.
How many faces and edges and vertices's does a rectangular pyramid have?
A rectangular-based pyramid has 5 faces, 8 edges, and 5 vertices. To check if the numbers are right, the Euler's rule can be used. The formula is Faces + Vertices = Edges + 2. Clearly, the sum of the faces and vertices, which is 10, is equal to the sum of the edges plus 2, which is also 10.

Is the surface area of the prism is the sum of the area of the base and lateral faces of the prism?
No, there are TWO bases.

What is the relationship between faces vertices and edges in prisms?
In a prism, the number of faces, vertices, and edges are related by the formula F + V - E = 2, known as Euler's formula. For a prism, which has two parallel and congruent faces connected by rectangular faces, the number of faces (F) is equal to the sum of the number of rectangular faces and the two congruent bases. The number of vertices (V) is equal to the number of corners where edges meet, and the number of edges (E) is equal to the sum of the edges around the bases and the edges connecting the corresponding vertices of the bases.
Surface area of a pentagonal prism?
Sum of the surface areas or each of its seven faces. Only the two pentagonal bases should have equal areas; there is no need for any of the other faces to have equal areas.
