Answer:
Option b. she left out one of the faces of the solid she should have simplified 2((5)(7))+2((6)(7))+2[1/2(5)(9.3)]+2[1/2(6)(9.2)]+(5)(6)
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the pyramid not including the base plus the surface area of the prism not including the top
so
[tex]SA=2((5)(7))+2((6)(7))+((5)(6))+2(\frac{1}{2}(5)(9.3))+2(\frac{1}{2}(6)(9.2))[/tex]
[tex]SA=285.7\ units^{2}[/tex]
