![]() ![]() All the other versions may be calculated with our triangular prism calculator. The only option when you can't calculate triangular prism volume is to have a 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 the 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) As a bonus, you will also be able to see the diagonal of the shape. To calculate either of these two unknowns, you simply need to enter the length (l), width (w), and height (h) of the shape, and the result will be generated in real-time. Triangular base: given two sides and the angle between them (SAS) Our cuboid calculator calculates the surface area of a cuboid as well as the volume. However, we don't always have the three sides given.
