To find the surface area of a triangular prism, we need to calculate the areas of the two triangular faces and the three rectangular faces.
1. Calculate the area of the two triangle faces:
Area = (1/2) * base * height
Area = (1/2) * 4 * 3 = 6 square cm
2. Calculate the area of the three rectangle faces:
a. Front face: 11 cm * 3 cm = 33 square cm
b. Arrow face: 11 cm * 5 cm = 55 square cm
c. Side face: 4 cm * 5 cm = 20 square cm
3. Add all the areas together:
6 + 33 + 55 + 20 + 20 = 134 square cm
Therefore, the surface area of the triangular prism is 134 square centimeters.
