The base of a rectangular prism is just an old familiar 2D rectangle.
All the old familiar 2D formulas for rectangles still apply to it.
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.
The base of a prism is always rectangular, so the area, A, =lw. l is length, w is width, of the base.

The formula for the area of the base of a rectangular prism is length multiplied by width. In mathematical terms, this can be represented as A = l x w, where A is the area of the base, l is the length of the base, and w is the width of the base. This formula is derived from the concept of finding the product of two sides of a rectangle to determine its area.
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.
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 the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. This formula calculates the total area of all six faces of the rectangular prism. It is derived from the formula for the surface area of a box, which consists of three pairs of identical rectangular faces.
