1. The area of one purple rectangle is:
2. The area of one green rectangle is:
3. The area of one pink rectangle is:
Therefore, in order to find the surface area of the rectangular prism, you can multiply each area calculated before by 2 and then you must add the products.
Then, you get that this is:
It means x should be divided by 8
x/8
