In this particular case, we're using the law of sines. Here's the formula for the triangle area that we need to use:Īrea = a² × sin(Angle β) × sin(Angle γ) / (2 × sin(Angle β + Angle γ)) We're diving even deeper into math's secrets! 😱 In this particular case, our triangular prism area calculator uses the following formula combined with the law of cosines:Īrea = Length × (a + b + √( b² + a² - (2 × b × a × cos(Angle γ)))) + a × b × sin(Angle γ) ▲ 2 angles + side between You can calculate the area of such a triangle using the trigonometry formula: Now it's the time when things get complicated. We used the same equations as in the previous example:Īrea = Length × (a + b + c) + (2 × Base area)Īrea = Length × Base perimeter + (2 × Base area) ▲ 2 sides + angle between

Where a, b, c are the sides of a triangular base This can be calculated using the Heron's formula:īase area = 0.25 × √, We're giving you over 15 units to choose from! Remember to always choose the unit given in the query and don't be afraid to mix them our calculator allows that as well!Īs in the previous example, we first need to know the base area. This calculator computes a triangular prisms area and volume when the triangle sides and prism height have been input. Choose the ▲ 2 angles + side between optionĢ.If you're given 2 angles and only one side between them If they give you two sides and an angle between them Input all three sides wherever you want (a, b, c). Calc Math Triangular Prism Calculator Calculate the volume of the Triangular Prism, surface area of the Triangular Prism and know the formulas. The surface area formula for a triangular prism is 2 (height x base / 2) + length x width1 + length x width2 + length x base, as seen in the figure below: A triangular prism is a stack of triangles, so the usually triangle solving rules apply when calculating the area of the bases.6 square units and (3 + 4 + 5)10 120 square units. From the net, we can see that there are two congruent triangle faces and three rectangular faces whose areas are as follows.


If they gave you all three sides of a triangle – you're the lucky one! For example, let the legs of a right triangle that is base of a triangular prism are 3 and 4 units and height of the prism is 10 units.
