I am doing the practice test for the CSWP-Sheet metal test. question 5 asks for the bounding box area. The answer I am getting is 42217.32 where as correct answer is 42963. I don't understand when Answer 4 is correct ie 185.55mm , I did not change any thing in the model so my model is correct then why my bounding box are is not correct. Any help is appreciated.   Thanks,
