What is the surface of the triangle prism?

1 answer

To find the surface area of a triangular prism, you need to calculate the surface area of each of its three rectangular faces and two triangular bases and add them together.

The formula to calculate the surface area of a triangular prism is:

Surface Area = 2 * base area of the triangle + perimeter of the triangle * height of the prism

First, you need to calculate the base area of the triangle. This can be done by using the formula for the area of a triangle, which is:

Area of a triangle = (1/2) * base * height

Then you multiply that result by 2 to get the base area of the two triangular bases.

Next, you need to calculate the perimeter of the triangle by adding up the lengths of all three sides.

Finally, multiply the perimeter of the triangle by the height of the prism and add it to the base area of the two triangular bases to get the total surface area of the triangular prism.
