[tex]D\:330\:cm^2[/tex]
1) In this problem, there is not a specific formula to find the surface area, so we need to do the net surface area of that solid.
2) Since the problem tells us that the area of each base is 65 cm² we can focus on the rectangles
Let's enlist the bases and the rectangles and their dimensions:
[tex]\begin{gathered} 2\times65=130 \\ 4\times10=40 \\ 3\times10=30 \\ 2\times10=20 \\ 2\times10=20 \\ 2\times10=20 \\ 7\times10=70 \\ ------- \\ A=330\:cm² \end{gathered}[/tex]
We cannot forget the rectangle on the "back" of that solid.
