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.
What is the sum of the faces an bases of an octagonal pyramid?
one base nine 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.
How do you find the area of a triangular wedge?
The surface area of a rectangular prism is the sum of the length times the width of its three pairs of faces. A triangular wedge is half of that.
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 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.
What are the angles on a triangular prism?
There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.

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.
When you add two triangular numbers why do they equal to a square number?
They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.They don't necesarily,3 is a triangular number and 10 is a triangular number.
