A = 2AB + AL
AB = area of the base
AL = lateral area = Perimeter X height
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?
its not i dont no why
It depends on what information you have.
Area=Bh when B=area of the base, and h=height of the prism/cylinder
I am not sure that a rectangular prism is in any position to care!
The Area of its base times the height of the shape.
Please be specific: Are you referring to surface area, volume? the length of one side?
area of base x height area of base x height
yes.
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
The base of a prism is always rectangular, so the area, A, =lw. l is length, w is width, of the base.
You must be thinking of a triangular prism. In that case, c is the length of the third side of the triangle at the end of the prism.
