Solve using substitution

Step-by-step explanation:

I hope this helps.

Area of two triangles: (1/2 x 4 x 6) x 2 = 24

Area of two rectangles on the roof: (5 x 12) x 2 = 120

Surface area of the rectangular prism: (2 x 8 x 6) + (2 x 8 x 12) = 96 + 192 = 288

Total surface area (not including the bottom cuz that wouldn't be painted) = 24 + 120 + 288 = 432
