The surface area of the rectangular prism can be calculated by finding the area of each individual rectangle and then adding them together.
From the given information, the dimensions of the rectangles are as follows:
1st rectangle: unknown
2nd rectangle: 9 cm x 5 cm
3rd rectangle: unknown
4th rectangle: 8 cm x unknown
5th rectangle: 8 cm x 5 cm
6th rectangle: 9 cm x unknown
To calculate the surface area, we need to find the dimensions of the unmarked rectangles. Using the dimensions given and the fact that opposite sides of rectangles are equal in length, we can find the missing dimensions:
1st rectangle: 5 cm x 8 cm
3rd rectangle: 5 cm x 8 cm
4th rectangle: 5 cm x 9 cm
6th rectangle: 8 cm x 9 cm
Now we can find the area of each rectangle:
1st rectangle: 5 cm x 8 cm = 40 cm^2
2nd rectangle: 9 cm x 5 cm = 45 cm^2
3rd rectangle: 5 cm x 8 cm = 40 cm^2
4th rectangle: 9 cm x 5 cm = 45 cm^2
5th rectangle: 8 cm x 5 cm = 40 cm^2
6th rectangle: 9 cm x 8 cm = 72 cm^2
Adding up the area of all 6 rectangles:
40 + 45 + 40 + 45 + 40 + 72 = 282 cm^2
Therefore, the surface area of the rectangular prism is 282 cm^2.
Use the image to answer the question.
An illustration shows the unfolded version of a rectangular prism composed of 6 rectangles. There are four adjoining rectangles positioned horizontally. The first and third are similar and smaller. The second and fourth are similar and bigger. The first rectangle is unlabeled. The second rectangle shares the top and bottom sides with two similar rectangles, one on each side. The top rectangle is labeled as 9 centimeters on the bottom and 5 centimeters on the right side. The right most rectangle is labeled 8 cm vertically on the right side.

My apologies for the mistake. Let's correct the calculation.
The dimensions of the rectangles are as follows:
1st rectangle: 5 cm x 8 cm
2nd rectangle: 9 cm x 5 cm
3rd rectangle: 5 cm x 8 cm
4th rectangle: 9 cm x 8 cm
5th rectangle: 8 cm x 5 cm
6th rectangle: 9 cm x 8 cm
Next, find the area of each rectangle:
1st rectangle: 5 cm x 8 cm = 40 cm^2
2nd rectangle: 9 cm x 5 cm = 45 cm^2
3rd rectangle: 5 cm x 8 cm = 40 cm^2
4th rectangle: 9 cm x 8 cm = 72 cm^2
5th rectangle: 8 cm x 5 cm = 40 cm^2
6th rectangle: 9 cm x 8 cm = 72 cm^2
Add up the area of all 6 rectangles:
40 + 45 + 40 + 72 + 40 + 72 = 309 cm^2
Therefore, the surface area of the rectangular prism is 309 cm^2.

2nd rectangle: 9 cm x 5 cm
3rd rectangle: 5 cm x 8 cm
4th rectangle: 9 cm x 8 cm
5th rectangle: 8 cm x 5 cm
6th rectangle: 9 cm x 8 cm
Now, calculate the area of each rectangle:
1st rectangle: 5 cm x 8 cm = 40 cm^2
2nd rectangle: 9 cm x 5 cm = 45 cm^2
3rd rectangle: 5 cm x 8 cm = 40 cm^2
4th rectangle: 9 cm x 8 cm = 72 cm^2
