The only option when you can't calculate triangular prism volume is having given triangle base and its height (do you know why? Think about it for a moment). Using law of sines, we can find the two sides of triangular base:Īrea = (length * (a + a * (sin(angle1) / sin(angle1+angle2)) + a * (sin(angle2) / sin(angle1+angle2)))) + a * ((a * sin(angle1)) / sin(angle1 + angle2)) * sin(angle2)

Triangular base: given two angles and a side between them (ASA) Using law of cosines, we can find the third triangle side:Īrea = length * (a + b + √( b² + a² - (2 * b * a * cos(angle)))) + a * b * sin(angle) Triangular base: given two sides and the angle between them (SAS) However, we don't always have the three sides given.

It's this well-known formula mentioned before: Our online tools will provide quick answers to your calculation and conversion needs. Length * Triangular base area given triangle base and height Our triangular prism calculator has all of them implemented, isn't it awesome? A general formula is volume = length * base_area the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. In the triangular prism calculator you can easily find out the volume of that solid.
