Which of the following describe a valid method for calculating the surface area of a triangular prism
One valid method for calculating the surface area of a triangular prism is to find the sum of the areas of all the faces, which include:
1. The two triangle faces: Calculate the area of one triangle face by using the formula A = 0.5 * base * height, then multiply by 2 since there are two triangle faces.
2. The three rectangular faces: Calculate the area of each rectangular face by multiplying the length and width, then multiply by 3 since there are three rectangular faces.
Finally, add the areas of all the faces together to find the total surface area of the triangular prism.
