2lw + 2lh + 2wh=surface area
but wouldn't that be surface area?
i don't think there is an formula though

Poor question as it does not specify the part of the prism's area: cross-section, one side, all 6 sides?
The above could be factorised to 2(lw + lh + wh)

Sure thing, honey. The formula for the area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Just plug in those values and you'll have your area faster than you can say "Golden Girls marathon."
If the base is a rectangle, use the formula for the area of a rectangle.
Depends whether you want the formula for surface area, volume, perimeter, size of sphere it would fit into etc... Please clarify next time.
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?
