Answer: A) 5 x 1/2
Step-by-step explanation: 5 x 1/2 yields 2.5, which is also the answer to 5 / 2.
You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.
