All the other cases can be calculated with our triangular prism calculator. The only case when we can't calculate triangular prism area is when the area of the triangular base and the length of the prism are given (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) In this article, we wil l learn about the formula to find the surface area of a triangular prism along with solving a few examples to provide a better understanding about the surface area of a triangular prism. Find the length of the triangular prism if its base is 6 cm, altitude is 9 cm and the area is 198. 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) Surface area of triangular prism is the total area covered by its surface in three dimensional plane. A polyhedron with three rectangular sides and two triangular bases is called a triangular prism. Find the total surface area of a triangular prism if its base is 5 cm, altitude is 7 cm and length is 8 cm. Triangular base: given two sides and the angle between them (SAS) However, we don't always have the three sides given. i.e. The lateral area for a triangular prism is the sum of areas of its side faces (which are 3 rectangles). area = length * (a + b + c) + (2 * base_area) = length * base_perimeter + (2 * base_area) The word 'lateral' means 'belonging to the side'.This fact allows us to see a relationship between the volume of a prism and the volume of a. If you want to calculate the surface area of the solid, the most well-known formula is the one given three sides of the triangular base : As a matter of fact, when this is the case, the pyramid takes up exactly 1/3 of the space in the prism. You can calculate that using trigonometry: Length * Triangular base area given two angles and a side between them (ASA) You can calculate the area of a triangle easily from trigonometry: Length * Triangular base area given two sides and the angle between them (SAS) If you know the lengths of all sides, use the Heron's formula to find the area of the triangular base: Length * Triangular base area given three sides (SSS) It's this well-known formula mentioned before: Length * Triangular base area given the altitude of the triangle and the side upon which it is dropped Our triangular prism calculator has all of them implemented. 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.
