There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
It is helpful because when you do the problem you know what to do.
Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.
The formula for finding the surface area of a rectangular prism is 2(wh + lw + lh), where w is width, h is height, and l is length. 3.14 is the value for pi, which is only used for circular objects, like circles, cylinders, and spheres. It has nothing to do with rectangular prisms. Click on the related link below for an illustration of the formula for the surface area of a rectangular prism.
by finding the area of the base (ex if a square its side times side) and then multiplying that product by the height :D

its not i dont no why
It depends on what information you have.
Area=Bh when B=area of the base, and h=height of the prism/cylinder
I am not sure that a rectangular prism is in any position to care!
The Area of its base times the height of the shape.
area of base x height area of base x height
yes.
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
The base of a prism is always rectangular, so the area, A, =lw. l is length, w is width, of the base.
You must be thinking of a triangular prism. In that case, c is the length of the third side of the triangle at the end of the prism.
