Length (l): Given as 8 cm.
Width (w): Visible as 5 cm (from the labeled rectangles).
Height (h): Not visible in the image.
Use the image to answer the question.
? cm ²
To calculate the area of a rectangle, we use the formula:
Area = Length x Width
In this case, the length (l) is given as 8 cm and the width (w) is visible as 5 cm. Therefore, we can calculate the area as:
Area = 8 cm x 5 cm
Area = 40 cm²
So the area of the rectangle is 40 cm².

I apologize for the error.
To calculate the area of a rectangular prism, we need to use the formula:
Area = 2lw + 2lh + 2wh
Given that the length (l) is 8 cm, width (w) is 5 cm, and height (h) is not visible, we can substitute these values into the formula:
Area = 2(8)(5) + 2(8)(h) + 2(5)(h)
Area = 80 + 16h + 10h
Area = 80 + 26h
Since the height (h) is not given, the area cannot be calculated without that value. If you can provide the height (h), I can help you calculate the total surface area of the rectangular prism.
H is 9 cm
Thank you for providing the height (h) as 9 cm.
Now that we have all the dimensions for the rectangular prism:
Length (l) = 8 cm
Width (w) = 5 cm
Height (h) = 9 cm
We can calculate the total surface area of the rectangular prism using the formula:
Total Surface Area = 2lw + 2lh + 2wh
Substitute the given values into the formula:
Total Surface Area = 2(8)(5) + 2(8)(9) + 2(5)(9)
Total Surface Area = 80 + 144 + 90
Total Surface Area = 314 cm²
Therefore, the total surface area of the rectangular prism is 314 cm².
