To solve this problem, we need to find the surface area of each individual face of the composite figure and then add them up.
Starting with the rectangular prism, we have:
- Front face: 13.7 x 11.5 = 157.55 cm^2
- Top face: 13.7 x 6.5 = 89.05 cm^2
- Right face: 11.5 x 6.2 = 71.3 cm^2
Now let's look at the missing rectangular prism section:
- Front face: 3 x 7.5 = 22.5 cm^2
- Top face: 3 x 6.2 = 18.6 cm^2
- Right face: 7.5 x 6.2 = 46.5 cm^2
Add up all these areas to get the total surface area:
157.55 + 89.05 + 71.3 + 22.5 + 18.6 + 46.5 = 405.5 cm^2
However, we need to subtract the area of the face where the missing section used to be. This face was a rectangle with dimensions 3 x 6.2, which has an area of 18.6 cm^2.
So the final surface area of the composite figure is:
405.5 - 18.6 = 386.9 cm^2
Rounding to one decimal place, we get:
386.9 ≈ 377.8 cm^2
Therefore, the answer is 377.8 cm^2.
Starting with the rectangular prism, we have:
- Front face: 13.7 x 11.5 = 157.55 cm^2
- Top face: 13.7 x 6.5 = 89.05 cm^2
- Right face: 11.5 x 6.2 = 71.3 cm^2
Now let's look at the missing rectangular prism section:
- Front face: 3 x 7.5 = 22.5 cm^2
- Top face: 3 x 6.2 = 18.6 cm^2
- Right face: 7.5 x 6.2 = 46.5 cm^2
Add up all these areas to get the total surface area:
157.55 + 89.05 + 71.3 + 22.5 + 18.6 + 46.5 = 405.5 cm^2
However, we need to subtract the area of the face where the missing section used to be. This face was a rectangle with dimensions 3 x 6.2, which has an area of 18.6 cm^2.
So the final surface area of the composite figure is:
405.5 - 18.6 = 386.9 cm^2
Rounding to one decimal place, we get:
386.9 ≈ 377.8 cm^2
Therefore, the answer is 377.8 cm^2.

An illustration shows a three dimensional composite figure formed by a rectangular prism with a missing section. The missing section is in the shape of two rectangular prisms. With the section removed, the figure resembles three steps. The top, right, and front faces are visible. The faces and edges that are not visible are indicated by dashed lines. The rectangular prism has a length of 12 centimeters at the bottom, a width of 2 centimeters, and a height of 18 centimeters. The top length of the rectangular prism is divided equally across the three steps. Each step has a length of 4 centimeters. The right side height of the rectangular prism is divided equally along the three steps. Each step has a height of 6 centimeters.

To solve this problem, we need to find the surface area of each individual face of the composite figure and then add them up.
Starting with the rectangular prism, we have:
- Front face: 12 x 18 = 216 cm^2
- Top face: (4 x 18) + (4 x 12) + (4 x 6) = 108 + 48 + 24 = 180 cm^2
- Right face: (6 x 18) + (6 x 4) + (6 x 2) = 108 + 24 + 12 = 144 cm^2
Now let's look at the missing rectangular prism sections:
- First missing section: Front face: 4 x 6 = 24 cm^2, Top face: 4 x 2 = 8 cm^2, Left face (shared with rectangular prism): 6 x 18 = 108 cm^2
- Second missing section: Front face: 4 x 12 = 48 cm^2, Top face: 4 x 2 = 8 cm^2, Left face (shared with rectangular prism): 6 x 18 = 108 cm^2
Add up all these areas to get the total surface area:
216 + 180 + 144 + 24 + 8 + 108 + 48 + 8 + 108 = 844 cm^2
However, we need to subtract the area of the face where the two missing sections meet. This face was a rectangle with dimensions 4 x 6, which has an area of 24 cm^2.
So the final surface area of the composite figure is:
844 - 24 = 820 cm^2
Therefore, the answer is 820 cm^2.
Starting with the rectangular prism, we have:
- Front face: 12 x 18 = 216 cm^2
- Top face: (4 x 18) + (4 x 12) + (4 x 6) = 108 + 48 + 24 = 180 cm^2
- Right face: (6 x 18) + (6 x 4) + (6 x 2) = 108 + 24 + 12 = 144 cm^2
Now let's look at the missing rectangular prism sections:
- First missing section: Front face: 4 x 6 = 24 cm^2, Top face: 4 x 2 = 8 cm^2, Left face (shared with rectangular prism): 6 x 18 = 108 cm^2
- Second missing section: Front face: 4 x 12 = 48 cm^2, Top face: 4 x 2 = 8 cm^2, Left face (shared with rectangular prism): 6 x 18 = 108 cm^2
Add up all these areas to get the total surface area:
216 + 180 + 144 + 24 + 8 + 108 + 48 + 8 + 108 = 844 cm^2
However, we need to subtract the area of the face where the two missing sections meet. This face was a rectangle with dimensions 4 x 6, which has an area of 24 cm^2.
So the final surface area of the composite figure is:
844 - 24 = 820 cm^2
Therefore, the answer is 820 cm^2.

To solve this problem, we need to find the surface area of each individual face of the two rectangular prisms and then add them up.
Starting with the large rectangular prism on the bottom, we have:
- Front face: 17 x 6.5 = 110.5 in^2
- Top face: 17 x 8.5 = 144.5 in^2
- Right face: 6.5 x 8.5 = 55.25 in^2
- Back face (not visible): 17 x 6.5 = 110.5 in^2

To solve this problem, we need to find the surface area of each individual face of the square prism and then subtract the surface area of the vertical rectangular portion that was removed from the bottom middle. Then, we need to multiply the remaining surface area by the depth of the magnet, which is 3 feet.
Starting with the square prism, we have:
- Front face: 10 x 10 = 100 ft^2
- Top face: 10 x 10 = 100 ft^2
- Right face: 10 x 5 = 50 ft^2
- Back face: 10 x 4 = 40 ft^2
- Left face: 10 x 5 = 50 ft^2
- Bottom face: 10 x 10 = 100 ft^2
Add up all these areas to get the total surface area of the square prism:
100 + 100 + 50 + 40 + 50 + 100 = 440 ft^2
Now let's look at the vertical rectangular portion that was removed from the bottom middle. This portion has a height of 5 feet and a width of 8 feet (since the remaining legs are each 4 feet wide). The length is equal to the side length of the square prism, which is 10 feet.
- Front face (not visible): 8 x 5 = 40 ft^2
- Top face (not visible): 10 x 8 = 80 ft^2
- Right face (not visible): 5 x 10 = 50 ft^2
- Back face (not visible): 10 x 5 = 50 ft^2
- Left face (not visible): 5 x 10 = 50 ft^2
- Bottom face (not visible): 8 x 10 = 80 ft^2
Add up all these areas to get the total surface area of the removed portion:
40 + 80 + 50 + 50 + 50 + 80 = 350 ft^2
Subtract the surface area of the removed portion from the surface area of the original square prism:
440 - 350 = 90 ft^2
Finally, multiply by the depth of the magnet, which is 3 feet:
90 x 3 = 270 ft^2
Therefore, the answer is 270 ft^2.
Starting with the square prism, we have:
- Front face: 10 x 10 = 100 ft^2
- Top face: 10 x 10 = 100 ft^2
- Right face: 10 x 5 = 50 ft^2
- Back face: 10 x 4 = 40 ft^2
- Left face: 10 x 5 = 50 ft^2
- Bottom face: 10 x 10 = 100 ft^2
Add up all these areas to get the total surface area of the square prism:
100 + 100 + 50 + 40 + 50 + 100 = 440 ft^2
Now let's look at the vertical rectangular portion that was removed from the bottom middle. This portion has a height of 5 feet and a width of 8 feet (since the remaining legs are each 4 feet wide). The length is equal to the side length of the square prism, which is 10 feet.
- Front face (not visible): 8 x 5 = 40 ft^2
- Top face (not visible): 10 x 8 = 80 ft^2
- Right face (not visible): 5 x 10 = 50 ft^2
- Back face (not visible): 10 x 5 = 50 ft^2
- Left face (not visible): 5 x 10 = 50 ft^2
- Bottom face (not visible): 8 x 10 = 80 ft^2
Add up all these areas to get the total surface area of the removed portion:
40 + 80 + 50 + 50 + 50 + 80 = 350 ft^2
Subtract the surface area of the removed portion from the surface area of the original square prism:
440 - 350 = 90 ft^2
Finally, multiply by the depth of the magnet, which is 3 feet:
90 x 3 = 270 ft^2
Therefore, the answer is 270 ft^2.

The surface area of a rectangular prism is given by:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism, respectively.
We are given that the width and height are both 9 cm, and the surface area is 432 cm^2. Substituting these values into the formula, we get:
432 = 2l(9) + 2(9)(9) + 2(9)l
Simplifying:
432 = 18l + 162 + 18l
432 = 36l + 162
36l = 270
l = 7.5
Therefore, the missing length of the rectangular prism is 7.5 cm.
SA = 2lw + 2lh + 2wh

Moving to the rectangular faces, we can use the given measurements to get:
- Right face: 4 x 5 = 20 cm^2
- Left face (not visible): 4 x 11 = 44 cm^2
- Top face (not visible): 3 x 11 = 33 cm^2
