If it is a triangular pyramid it would be (1/2bh)4
A triangular prism is (1/2bh)5, or (base x height divided by 2)times 4
Sketch a net of it and then work out the area of each of its 5 netted components and then add them together
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
Calculus can be used to find the surface area of any object given that you know the equation describing said object. It's usually easier to find the area from experiment or through using a combination of existing models to approximate the surface area
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
Area = base*height
A quadrilateral does not have a surface area because it is not a voluminous figure.
The answer depends on what you wish to work out: the angles, height, surface area, volume. Also, you need more information: the vertical or inclined height and whether or not the pyramid is a right pyramid.

Find the area of one of the sides and then multiply it by 3 (3 sides to a triangular pyramid)Then work out the area of the base of the pyramid, and add it to the total area of all the sides.Area of a triangle = Base x Height / 2

It says so in the formula
Area = base*height
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
a formula is alway correct
