PRACTICAL MATH HELP NEEDED?

Thank you in advance. I have been very sick lately and missed a lot of school so these questions have been difficult for me. Also, math was never my strong suit even before I got sick. I have all A's other than this class. Any help or explanations are much appreciated.

Answer:

10. B] sorry not sure! 11. A] scale of blueprint is 1in=18ft which means every 1in on the blueprint measures 18ft in reality. so, 1in2=324ft2 190*324=61560ft2 12. A] every 10 parts of the actual silo=1 part of the model every 1000m3 of the silo=1m3 of the model every 1m3 of the silo=1/1000m3 of the model 550m3 of the silo=(550/1000) =0.55m3 and if u truly want to understand,there is no better way to try to do it yourself. Even though u would have difficulty first but you will do better.
