Area of the top of the rectangular prism: 12" x 9" = 108 sq inches
Area of the side of the rectangular prism: 6" x 9" = 54 sq inches
Area of the front of the rectangular prism: 12" x 6" = 72 sq inches
Total surface area of the rectangular prism: 2(108) + 2(54) + 2(72) = 216 + 108 + 144 = 468 sq inches
