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 bigger. The second and fourth are similar and smaller. The third rectangle is labeled 4 inches on the top horizontally. The fourth rectangle is labeled as 2.25 inches on the top and 8 inches on the right side. The first rectangle shares the top and bottom sides with two similar rectangles, one on each side.

What is the surface area of the rectangular prism?

To find the surface area of the rectangular prism, we need to calculate the area of each of the 6 rectangles and then add them together.

The first rectangle:
- Dimensions: 4 inches x 2.25 inches
- Area: 4 inches x 2.25 inches = 9 in²

The second rectangle:
- Dimensions: 4 inches x 8 inches
- Area: 4 inches x 8 inches = 32 in²

The third rectangle:
- Dimensions: 4 inches x 2.25 inches
- Area: 4 inches x 2.25 inches = 9 in²

The fourth rectangle:
- Dimensions: 4 inches x 8 inches
- Area: 4 inches x 8 inches = 32 in²

The fifth rectangle (same as first):
- Dimensions: 4 inches x 2.25 inches
- Area: 4 inches x 2.25 inches = 9 in²

The sixth rectangle (same as second):
- Dimensions: 4 inches x 8 inches
- Area: 4 inches x 8 inches = 32 in²

Adding all the areas together:
9 in² + 32 in² + 9 in² + 32 in² + 9 in² + 32 in² = 123 in²

Therefore, the surface area of the rectangular prism is 123 in².

I apologize for the mistake in my previous response. Let's recalculate the surface area of the rectangular prism.

Each rectangular prism has 6 faces. To find the surface area of a rectangular prism, we need to calculate the areas of all 6 faces and then sum them up.

Face 1 (4 in x 2.25 in): 4 in x 2.25 in = 9 in²
Face 2 (4 in x 2.25 in): 4 in x 2.25 in = 9 in²
Face 3 (4 in x 8 in): 4 in x 8 in = 32 in²
Face 4 (4 in x 8 in): 4 in x 8 in = 32 in²
Face 5 (2.25 in x 8 in): 2.25 in x 8 in = 18 in²
Face 6 (2.25 in x 8 in): 2.25 in x 8 in = 18 in²

Total surface area:
9 in² + 9 in² + 32 in² + 32 in² + 18 in² + 18 in² = 118 in²

Therefore, the correct surface area of the rectangular prism is 118 in². Thank you for bringing this to my attention.
