The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:
[tex](base)*(height)/2[/tex]
So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)
Thank you for the question! I hope this helped! Have an amazing day!! :D
