Area of triangular prism calculator7/13/2023 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. Formula for the volume of a triangular prism The formula to calculate the volume for prisms is always the same: Volume prism Area base × Length In this case. 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 surface area calculator helps you find the area of the most common three-dimensional solids. This can be calculated using the Heron's formula:īase area = 0.25 × √, Find the areas of each of the three rectangular faces, using the formula for the area of a rectangle: length x width. 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. Here are the steps to compute the surface area of a triangular prism: 1.
