How would I find the surface area of the triangular prism

To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area. Next, multiply the base times height for the area of the triangles (bh), and add the three sides of the triangle (s1 + s2 + s3). Then, multiply the sum of the triangle sides by the height of the prism (H) and add the values together for the answer, making sure to include the appropriate unit of measurement.
