Understanding how to find the surface area of a triangular prism can be simple with these steps:

Step 1: | Identify the dimensions of the triangular base (base and height) and the length of the prism. |

Step 2: | Calculate the area of the triangular base using the formula: (Base * Height) / 2. |

Step 3: | Determine the perimeter of the triangular base by adding all three sides. |

Step 4: | Multiply the perimeter by the prism’s length to get the lateral surface area. |

Step 5: | Sum the areas of the two triangular bases and the lateral area to find the total surface area. |
