What are you having trouble with? Can you do the rectangular part of the figure?

anonymous · Answer

Total Surface Area = (square cube) + (Triangle pyramid) 
it's not really a square cube but I just wanted to point out what I am trying to find
so TSA = (8x2x2 + 8x2x2 + 8x8) + ( 1/2 x 8 x 3) x 4
           = (128) + (48)
           = 176 mm^2

That's good too.

remember that we do not need to include the area for the bottom surface of the pyramid and the top lid of the so called "square cube" as I do not know what it is actually called.
