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)

Oh, dude, it's like super simple. So, to find the area of a rectangular prism, you just need to calculate the total surface area by adding up the areas of all the individual faces. It's like, you find the area of the base (length x width) and then multiply it by the height of the prism. Voilà, you've got the area of a rectangular prism!
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?
