The base of a prism is always rectangular, so the area, A, =lw. l is length, w is width, of the base.
Squared. When you find surface area, you are only finding the area of the shapes that make up the three-denominational shape.
Surface area = 2LW + 2(L+W)H
area of base x height area of base x height
2(l*w)+2(w*h)+2(l*h)=surface area
I am not sure that a rectangular prism is in any position to care!
its not i dont no why
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?
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.
It is helpful because when you do the problem you know what to do.

surface area of a rectangular prism is the formula: 2lw+2wh+2lh
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.
Oh, dude, it's like super simple. So, to find the area of a rectangular prism, you just need to calculate the total surface area by adding up the areas of all the individual faces. It's like, you find the area of the base (length x width) and then multiply it by the height of the prism. Voilà, you've got the area of a rectangular prism!
