Help with these 4 problems

Answer 1

10. A 288cm^2
11. C 52
12. D 110 pi
13. A 15   Explanation because to me this what the most tricky lateral area is the surface area of all the side but the top and bottom. The top and bottom faces of a rectangular prism are the same so if you now the surface area and the lateral surface area subtract them you get 30 that is the top and bottom faces area. half that you get 15 that is 1 face.
