What is a valid method for calculating the surface areas of a triangular prism

Answer 1

One valid method for calculating the surface area of a triangular prism is by using the formula:

SA = 2*(area of base triangle) + (perimeter of base triangle) * (height of prism)

To find the area of the base triangle, you can use the formula for the area of a triangle, which is 0.5 * (base * height). To find the perimeter of the base triangle, simply add the lengths of all three sides of the triangle.

Once you have calculated the area of the base triangle and the perimeter of the base triangle, as well as the height of the prism, plug these values into the formula given above to calculate the total surface area of the triangular prism.
