On a piece of paper, graph this system of inequalities. Then determine which region contains the solution to the system.

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 surface area would be 576 because you multiply all the numbers then multiply that number by 6
