A triangular prism has a base with three sides, and also a length.
You have only listed three numbers.
In any case, I assume you can find the area of a triangle and a rectangle.
The prism's surface comprises 2 triangles and three rectangles.
So add up all those areas.

If the base is an isosceles triangle with base=15 and altitude 8, then the two congruent sides are 17. So the area would be
2(8*15/2) + 17*15 + 17*15 + 8*15
2(8*15/2) + 17*15 + 17*15 + 8*15
