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 area of the second rectangle is labeled 24 square inches. The third rectangle shares the top and bottom sides with two similar rectangles, one on each side. The area of the top rectangle is labeled as 54 square inches and the area of the third rectangle is labeled as 36 square inches.
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 rectangular face and add them up. In this case, we have six rectangular faces:
- The first and fourth faces both have an area of 54 square inches (since they are the same size and shape as the top and bottom faces).
- The second face has an area of 24 square inches.
- The third face has an area of 36 square inches.
- The fifth and sixth faces are the same size and shape as the second and fourth faces, so they each have an area of 24 square inches.
To find the total surface area, we add all of these areas:
54 + 54 + 24 + 36 + 24 + 24 = 216 square inches
So the surface area of the rectangular prism is 216 square inches.
Wouldn't it be 54 + 54 + 24 + 36 + 24 + 36 = 228?
You are correct, I apologize for my mistake. The total surface area would be:
54 + 54 + 24 + 36 + 24 + 36 = 228 square inches.
Thank you for catching that error!
