To find the surface area of a triangular prism, we need to find the areas of all the individual faces and then add them together.
A triangular prism has 5 faces: two triangular bases and three rectangular lateral faces.
First, find the area of the two triangular bases. The formula for the area of a triangle is 1/2 * base * height. Since they are both triangles, the bases will be the same as one side of the rectangle and the height of the triangle.
Next, find the area of the three rectangular lateral faces. The formula for the area of a rectangle is length * width. One side of the rectangle is the same as the height of the triangle and the other side is the width of the triangle.
Add up all the areas to find the total surface area of the triangular prism.
Let's say the triangular prism has dimensions of:
Base of triangle: 10 cm
Height of triangle: 8 cm
Length of prism: 12 cm
Width of prism: 6 cm
Height of prism: 5 cm
Base area: 1/2 * 10 cm * 8 cm = 40 cm²
Two bases: 2 * 40 cm² = 80 cm²
Lateral faces area:
2 lateral faces = 12 cm * 8 cm = 96 cm²
1 lateral face = 6 cm * 8 cm = 48 cm²
Total lateral faces area = 96 cm² + 48 cm² = 144 cm²
Total surface area: 80 cm² + 144 cm² = 224 cm²
Therefore, the surface area of the triangular prism is 224 square centimeters.
Given the choices provided, none of them are correct, but the closest answer is 260 square centimeters.

To find the surface area of a triangular prism, we need to calculate the area of each face and then add them all together.
Let's use the dimensions provided:
Base of the triangle = 10 cm
Height of the triangle = 8 cm
Length of the prism = 10 cm
Width of the prism = 6 cm
Height of the prism = 10 cm
1. Calculate the area of the triangular base:
Area = (1/2) * base * height
Area = (1/2) * 10 cm * 8 cm
Area = 40 square cm
2. Calculate the area of the two triangular bases:
Total base area = 2 * 40 square cm
Total base area = 80 square cm
3. Calculate the area of the three rectangular lateral faces:
Face 1: Length * Height = 10 cm * 8 cm = 80 square cm
Face 2: Width * Height = 6 cm * 8 cm = 48 square cm
Face 3: Length * Height = 10 cm * 10 cm = 100 square cm
Total lateral faces area = 80 square cm + 48 square cm + 100 square cm
Total lateral faces area = 228 square cm
4. Add the total base area and total lateral faces area to find the surface area of the triangular prism:
Surface area = Total base area + Total lateral faces area
Surface area = 80 square cm + 228 square cm
Surface area = 308 square cm
Therefore, the correct surface area of the triangular prism is 308 square centimeters.
None of the given answer choices are correct.

Using the same dimensions provided:
Base of the triangle = 10 cm
Height of the triangle = 8 cm
Length of the prism = 10 cm
Width of the prism = 6 cm
Height of the prism = 10 cm
1. Calculate the area of the triangular base:
Area = (1/2) * base * height
Area = (1/2) * 10 cm * 8 cm
Area = 40 square cm
2. Calculate the area of the two triangular bases:
Total base area = 2 * 40 square cm
Total base area = 80 square cm
3. Calculate the area of the three rectangular lateral faces:
Face 1: Length * Height = 10 cm * 8 cm = 80 square cm
Face 2: Width * Height = 6 cm * 8 cm = 48 square cm
Face 3: Length * Height = 10 cm * 10 cm = 100 square cm
Total lateral faces area = 80 square cm + 48 square cm + 100 square cm
Total lateral faces area = 228 square cm
4. Add the total base area and total lateral faces area to find the surface area of the triangular prism:
Surface area = Total base area + Total lateral faces area
Surface area = 80 square cm + 228 square cm
Surface area = 308 square cm
Therefore, the correct surface area of the triangular prism is 308 square centimeters.
Among the given answer choices, the closest one is 320 square centimeters.

To find the surface area of the net of the triangular prism, we need to first calculate the individual areas of all the faces and then add them together.
Given the dimensions provided:
Base of the triangle = 17 m
Height of the triangle = 15 m
Length of the prism = 17 m
Width of the prism = 11 m
Height of the prism = 16 m
1. Calculate the area of the triangular base:
Area = (1/2) * base * height
Area = (1/2) * 17 m * 15 m
Area = 127.5 square meters
2. Calculate the area of the two triangular bases:
Total base area = 2 * 127.5 square meters
Total base area = 255 square meters
3. Calculate the area of the three rectangular lateral faces:
Face 1: Length * Height = 17 m * 16 m = 272 square meters
Face 2: Width * Height = 11 m * 16 m = 176 square meters
Face 3: Length * Height = 17 m * 16 m = 272 square meters
Total lateral faces area = 272 square meters + 176 square meters + 272 square meters
Total lateral faces area = 720 square meters
4. Add the total base area and total lateral faces area to find the surface area of the net of the triangular prism:
Surface area = Total base area + Total lateral faces area
Surface area = 255 square meters + 720 square meters
Surface area = 975 square meters
Therefore, the surface area of the net of the triangular prism is 975 square meters.
Given the choices provided, none of them match the calculated value of 975 square meters.
