How to find surface area of triangular prism

answer:

triangular base: given two sides and the angle between them (sas)

using law of cosines, we can find the third triangle side:

area = length * (a + b + √( b² + a² - (2 * b * a * cos( + a * b * sin(angle)

triangular base: given two angles and a side between them (asa)

using law of sines, we can find the two sides of triangular base:

area = (length * (a + a * (sin(angle1) / sin(angle1+angle2)) + a * (sin(angle2) / sin(angle1+ + a * ((a * sin(angle1)) / sin(angle1 + angle2)) * sin(angle2)
