To solve for the total surface area of the figure, we need to calculate the surface area of each individual face (front, back, top, bottom, left, right) and then add them all together. Here is the breakdown:
Front face (rectangular prism): 13.7 cm x 11.5 cm = 157.55 cm²
Top face (rectangular prism): 13.7 cm x 6.2 cm = 84.94 cm²
Right face (rectangular prism): 11.5 cm x 4 cm = 46 cm²
Left face (rectangular prism): 11.5 cm x 4 cm = 46 cm²
Back face (inside the missing section): 7.5 cm x 7.5 cm = 56.25 cm²
Bottom face (inside the missing section): 7.5 cm x 3 cm = 22.5 cm²
Now, add all these values together to get the total surface area:
157.55 cm² (front) + 84.94 cm² (top) + 46 cm² (right) + 46 cm² (left) + 56.25 cm² (back) + 22.5 cm² (bottom) = 413.24 cm²
Therefore, the total surface area of the figure is 413.24 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.
