Question

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.

To find the surface area of the rectangular prism, we need to calculate the total area of each individual rectangle and then add them up.

First rectangle: unknown dimensions, area = x

Second rectangle: 9 cm x 5 cm = 45 cm²
Third rectangle: same as first rectangle, so area = x

Fourth rectangle: 9 cm x 8 cm = 72 cm²
Fifth rectangle (the bottom side of the rectangular prism): same as second rectangle, so area = 45 cm²
Sixth rectangle (the back side of the rectangular prism): same as fourth rectangle, so area = 72 cm²

Adding up the areas of all six rectangles:
x + 45 cm² + x + 72 cm² + 45 cm² + 72 cm² = 2x + 234 cm²

Since x represents the area of the first and third rectangles, we can combine them:
2x + 234 cm² = 4x + 234 cm²

Therefore, the total surface area of the rectangular prism is 4x + 234 cm².

I apologize for the mistake. Let's correct the calculation:

The surface area of a rectangular prism can be calculated by finding the area of each face and adding them up.

For the first rectangle: let's label the dimensions as length (l) and width (w).
Area = l * w = x

For the second rectangle: dimensions are 9 cm x 5 cm = 45 cm²
For the fourth rectangle: dimensions are 9 cm x 8 cm = 72 cm²
For the third rectangle (similar to the first): area = x
The fifth rectangle (the bottom) and sixth rectangle (the back) are the same as the second and fourth rectangles, respectively.

Adding up the areas:
x + 45 cm² + x + 72 cm² + x + 45 cm² + 72 cm² = 3x + 234 cm²

Therefore, the total surface area of the rectangular prism is 3x + 234 cm².
