This is three 5x5x3 blocks. Each block will have 2 faces that are 5*5 for surface area and 4 sides that are 3*5 for surface area.  3(2*5*5+4*3*5) would be the formula for all of them at once. So,
3(50+60)
3(110)
330 units^2 for the surface area.

I believe that I did that correctly, I just quickly glanced and didn't make sure the 3 5x5x3 blocks was 100% correct.
