Well when you find the surface area of a rectangular prism you must use this formula: SA=2lw+2lh+2wh. Key: l= length h=height w=width. So in this case you can write the formula out like this: SA=2x120+2x48+2x40. So just multiply all of of those and you will get the correct answer. If you have any questions let me know. (It is not the same answer as the first person said) it would be helpful if you marked this brainliest!
