If W = 11 units, X = 3 units, Y = 8 units, and Z = 10 units, what is the surface area of the right rectangular pyramid shown above?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The correct answer is 7
