If no top:
If all from one rectangular sheet then:
length has to be 18+2*9
width has to be 15+2*9
I suppose you could say you save the four 9 by 9 corner cutouts, but not really.
If you make the bottom out of 15*18
and then the walls out of one long strip which is 9 *(2*18+22*15) then you save those wasted corners but have to use more corner tape.

if the top is included ...
SA = 2(15x9) + 2(15x18) + 2(9x18)
SA = 2(15x9) + 2(15x18) + 2(9x18)
