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.
(1 point)
To find the total surface area of the figure, we need to calculate the surface area of the rectangular prism and subtract the surface area of the missing section.
First, calculate the surface area of the rectangular prism:
Surface area = 2lw + 2lh + 2wh
Surface area = 2(13.7)(11.5) + 2(13.7)(6.2) + 2(11.5)(6.2)
Surface area = 607.1 + 169.4 + 142.3
Surface area = 918.8 square centimeters
Next, calculate the surface area of the missing section:
Surface area = 2lw + 2lh + 2wh
Surface area = 2(7.5)(3) + 2(7.5)(4) + 2(3)(4)
Surface area = 45 + 60 + 24
Surface area = 129 square centimeters
Finally, subtract the surface area of the missing section from the surface area of the rectangular prism:
Total surface area = 918.8 - 129
Total surface area = 789.8 square centimeters
Therefore, the total surface area of the figure is 789.8 square centimeters.
