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.
It's not.. It may be, depending why, but there isn't a set formula for it. You just use the fundamental rectangle-area formulae & string them together.
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.

well finding the surface area of one face is just like finding the area of a flat rectangle, so all you have to do is find the area of each face and add them up into one sum. i believe that the formula is 2ab + 2bc + 2ac
its not i dont no why

I am not sure that a rectangular prism is in any position to care!

The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.

Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...
The surface area of a rectangular prism can be calculated by adding the areas of all six faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively. This formula accounts for the two faces of each dimension (length, width, and height) on the rectangular prism.
what is the formula to finding the total surface area of a rhomboid?!
2lw + 2lh + 2wh
A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.
