    area of the rectangle prism=2(7*3+16*7+16*3) =362 in^2 area of prism=3*6+5*6+6*6+1/2*2*5*3 =99 in^2 so total area=99+362

    so for the one top triangle, its area should be counted.... but it can also be used to fill the bottom triangular hole on the rectangular prizm. So "the two triangle pieces "1/2*2*5*3" are double-counted" and the ans should be 446 instead :)
