find it by adding all the individual surface areas together. there are 2 of each side and there are 3 different sides.
SA=2%28%28LW%29%2B%28LH%29%2B%28WH%29%29
L=9
W=8
H=7
SA=2%28%289%2A8%29%2B%289%2A7%29%2B%288%2A7%29%29
SA=2%28%2872%29%2B%2863%29%2B%2856%29%29
SA=2%28191%29
SA=382
surface area is 382cm
