Answer 2

@galipso T.A

I know it makes no sense

Answer 3

Total Area. you need to find the area's of each face, then add them together. also, are you doing AOA? the picture looks familiar.
area of a rectangle: b*h
area of an equilateral: http://www.mathwords.com/a/a_assets/area%20equilateral%20triangle%20formula.gif


so, 6*3 + 6*3 + 6*3 + 9sqrt3/4 + 9sqrt3/4 and there's you're T.A

in the form they want you to put it in, i think they want you to split it up. so
i'll do the first part.
6*3 + 6*3 + 6*3 + 9sqrt3/4 + 9sqrt3/4 = [5][4] + [ ]/[ ] *squared*
