@jhonyy9 do you can help ? ty

Answer 5

?

Answer 6

I do not think it is a or D

Answer 7

so step by step
1. these two lateral sides in the form of a square with sides length ,,a" has area a*a=a^2
so 2a^2
2. there are 3 rectangles with length equal ,,b" and width equal ,,a" so the area of them will be 3*b*a
3. area of this rectangle from the top will be a*b - 3(c*c) = a*b -3c^2
4. these 3 cubes has surface area 5*c^2 so total 3*5*c^2

and now just you need add these results from these 4 steps

hope helped easy understandably
