What is the surface area of this triangular prism rounded to the nearest tenth?

22.9

Step-by-step-explanation:

multiply 2.5*2=5multiply 5.1*2=10.2multiply 6.8*2=13.6multiply 8.5*2=17

add all final results which equal...45.8

Then since it's a triangle u have to either divide by 2 or multiply by 1/2

either way u should get 22.9

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.
