To find the surface area of the triangular prism, we need to calculate the area of each individual shape and then add them all together.
1. The area of the middle rectangle (front and back) is 8mm * 7mm * 2 = 112mm^2
2. The area of the two side rectangles (left and right) is 6mm * 7mm * 2 = 84mm^2
3. The area of the two triangles is (1/2) * base * height = (1/2) * 6mm * 8mm * 2 = 48mm^2
Therefore, the total surface area of the triangular prism is 112mm^2 + 84mm^2 + 48mm^2 = 244mm^2.
Question
Use the image to answer the question.
An illustration shows a two-dimensional net of a triangular prism with all of its sides open and visible. The net appears as three vertical rectangles joined one on top of the other. All 4 sides of the middle rectangle are drawn with dashed lines. The width of the rectangles is 7 millimeters. The length of the middle rectangle is 8 millimeters. Two right triangles adjoin the middle rectangle on the left and the right, with the perpendicular sides measuring 6 millimeters and the hypotenuse measuring 10 millimeters.
Using the net of the prism shown, what is its surface area?

No, the correct answer is 244 mm^2.
no its not because all of the rectangles are the same area
I apologize for the mistake. Let's recalculate the surface area of the triangular prism using the corrected information:
1. The area of the middle rectangle (front and back) is 8mm * 7mm * 2 = 112mm^2
2. The area of the two side rectangles (left and right) is 7mm * 7mm * 2 = 98mm^2
3. The area of the two triangles is (1/2) * base * height = (1/2) * 6mm * 8mm * 2 = 48mm^2
Now, adding up the areas:
112mm^2 (middle rectangle) + 98mm^2 (side rectangles) + 48mm^2 (triangles) = 258mm^2
Therefore, the correct surface area of the triangular prism is 258 mm^2. Thank you for pointing out the error.

that is still wrong for all three rectangles you would do 7 times 8
Apologies for the oversight. Let's calculate the surface area of the triangular prism correctly:
1. The area of the front and back rectangles (middle rectangle): 7mm * 8mm * 2 = 112mm^2
2. The area of the side rectangles (left and right): 6mm * 7mm * 2 = 84mm^2
3. The area of the two triangles: 1/2 * 6mm * 8mm * 2 = 48mm^2
Now, sum up the areas:
112mm^2 (middle rectangle) + 84mm^2 (side rectangles) + 48mm^2 (triangles) = 244mm^2
Therefore, the correct surface area of the triangular prism is 244 mm^2. Thank you for your patience.
