Use the image to answer the question.
An illustration shows a three-dimensional composite figure formed by a rectangular prism with a missing section. The missing section is also in the shape of a rectangular prism. The top, right, and front faces of the figure are visible. "The faces and edges that are not visible are indicated by dashed lines. The rectangular prism has a length of 13.7 centimeters and a height of 11.5 centimeters. The missing section is removed from the bottom right corner of the rectangular prism. The missing section is a rectangular prism that shares a width of 3 centimeters with the rest of the figure. The missing rectangular prism section has a length of 7.5 centimeters and a height of 7.5 centimeters. The remaining length to the left of the missing section both measures 6.2 centimeters. The remaining height above the missing section measures 4 centimeters.
Solve for the total surface area of the figure.
377.8 cm2
353.8 cm2
365.8 cm2

Surface area of rectangular prism:
Top and bottom faces: 2(13.7 * 11.5) = 315.1 cm^2
Front and back faces: 2(13.7 * 6.2) = 169.6 cm^2
Right and left faces: 2(11.5 * 6.2) = 142.3 cm^2
Total surface area of rectangular prism: 315.1 + 169.6 + 142.3 = 627 cm^2
Surface area of missing section:
Front and back faces: 2(7.5 * 3) = 45 cm^2
Top and bottom faces: 2(7.5 * 4) = 60 cm^2
Right face: 3 * 4 = 12 cm^2
Total surface area of missing section: 45 + 60 + 12 = 117 cm^2
Total surface area of the figure: 627 - 117 = 510 cm^2
Therefore, the correct answer is not provided in the options given.
