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?
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.
To prove that two lines cut by a transversal are parallel, one must show that
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.
what is the formula to finding the total surface area of a rhomboid?!
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...
2lw + 2lh + 2wh
