Okay! To find the surface area of a triangular prism, I need to add up the areas of all the flat surfaces on the prism.
First, I need to find the area of the two triangular bases. To do that, I need to multiply the base of the triangle by its height and then divide that by 2.
Then, I need to find the area of the three rectangular sides. To do that, I need to multiply the length of the side by the height of the prism.
Finally, I add up the areas of the two triangles and three rectangles to get the total surface area of the triangular prism.
Use your net to find the surface area for your triangular prism.
