To calculate the surface area of a triangular prism, you need to calculate the areas of the three rectangular faces and the two triangular faces.
1. Start by calculating the area of one of the rectangular faces. You can do this by multiplying the length and width of the face. In this case, the length of the rectangular face is 8 and the width is 9. So the area of one rectangular face is 8 x 9 = 72 square units.
2. Next, calculate the area of the second rectangular face using the dimensions of 9 and 7. So the area of the second rectangular face is 9 x 7 = 63 square units.
3. Finally, calculate the area of the third rectangular face using the dimensions of 8 and 7. So the area of the third rectangular face is 8 x 7 = 56 square units.
4. Now, calculate the areas of the two triangular faces. The formula to calculate the area of a triangle is (base x height) / 2. In this case, the base of the triangle is 9 and the height is 14. So the area of one triangular face is (9 x 14) / 2 = 63 square units. Since there are two triangular faces, the total area of the triangular faces is 2 x 63 = 126 square units.
5. Finally, add up the areas of all the faces to find the total surface area. 72 (1st rectangular face) + 63 (2nd rectangular face) + 56 (3rd rectangular face) + 126 (total area of the two triangular faces) = 317 square units.
Therefore, the surface area of the triangular prism with dimensions 8, 9, 7, 14, and 11 is 317 square units.
