To find the area :_
1/2 Breadth * Height
(half multiplied by breadth multiplied by height)
Try again.
Here is the correct answer.
Area = AL + 2AB
AL = area of the laterals = perimeter of base X height
AB = area of the base

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
