Front Triangle (49.5) + Back Triangle (49.5) + Left Rectangle (192) + Right Rectangle (192) + Bottom Rectangle (144)
49.5 + 49.5 + 192 + 192 + 144 = 627 m2

Use the net to find the surface area of the solid below.
Square base (36) + Each triangle (27) (include all four)
36 + 27 + 27 + 27 + 27 = 144 ft2
36 + (4 x 27) = 144 ft2
