The surface area (SA) is composed of 5 sides so you would create an equation that adds the areas of the individual sides and sets that equal to SA.  "x" is in all of them.  I'll show you one of the sides and then you can do the rest.  The slanted down side has an area of 13 times "x" or 13x.  The other sides are found in the same way.  Add all five up and set to SA.  Solve for "x".  Then you're done.

Sorry, "x" is in THREE of them, but you still solve in the same way as described above.
