To find the total surface area of the figure, we first need to find the surface area of each individual rectangular prism.
The surface area of the rectangular prism (without the missing section) is given by:
2lw + 2lh + 2wh
= 2(13.7)(11.5) + 2(13.7)(4) + 2(11.5)(4)
= 510.1 + 109.8 + 92
= 711.9 cm²
The surface area of the missing section (rectangular prism) is given by:
2lw + 2lh + 2wh
= 2(6.2)(3) + 2(6.2)(4) + 2(3)(4)
= 37.2 + 49.6 + 24
= 110.8 cm²
Therefore, the total surface area of the figure is the sum of the surface areas of both rectangular prisms:
711.9 + 110.8
= 822.7 cm²
So, the total surface area of the figure is 822.7 cm².
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.
