To find the surface area of a triangular prism, we need to calculate the area of each face and add them up.
1. Calculate the area of the two triangular faces:
Area = 0.5 * base * height
Area = 0.5 * 11 * 3 = 16.5 square cm
Area = 0.5 * 4 * 3 = 6 square cm
2. Calculate the area of the three rectangular faces:
Area = length * height
Area = 11 * 4 = 44 square cm
Area = 4 * 5 = 20 square cm
Area = 5 * 11 = 55 square cm
3. Add up the areas of all the faces:
16.5 + 6 + 44 + 20 + 55 = 141.5 square cm
Therefore, the surface area of the triangular prism is 141.5 square centimeters.
None of the given options match the calculated surface area, so there may have been a mistake in the calculations.
