whats the formula for the surface area of a triangular prism.

The formula for the surface area of a triangular prism is:

SA = 2(0.5 * b * h) + (l * w) + (l * s1) + (l * s2)

where:
SA = Surface Area
b = base of the triangle
h = height of the triangle
l = length of the prism
w = width of the prism
s1 and s2 = side lengths of the triangle
