This is done when you have three sides given. Volume = length * a² * sin(β) * sin(γ) / (2 * sin(β + γ)) Surface area of a triangular prism The most prevalent formula for calculating the surface area is the following:Īrea = length * (a + b + c) + (2 * base_area) = length * base_perimeter + (2 * base_area)
If you have a triangular prism where a side is between two angles ( ASA), working out the area again involves trigonometry: With two sides and an angle in between ( SAS), it’s a case of using trigonometry when calculating the area:Ĥ. When you know each length of the three sides ( SSS), it’s a case of using Heron’s formula to work out the triangular base’s area: Thankfully our calculator has all four techniques implemented.ġ.ğirst of all, there’s the previously mentioned formula for the triangle’s height and base:Ģ. The one parameter that’s always necessary is the prism length, while there are four methods for calculating the base – triangle area. Volume = length * base_area is a general formula for triangular prism volume. Volume of a triangular prism Finding the volume of a triangular prism is easy with our calculator. However, what if you don’t possess the base and height of the triangle? Or if you don’t have the triangular base’s sides, yet you need to discover the surface area? Well don’t worry: there are different triangular prism formulas as found below. The base area of the triangular prism is represented by base_area. The a, b and c letters are the respective sides of the triangle. While the length is, you guessed it, the prism’s length.Īrea = Length * (a + b + c) + (2 * base_area)
Volume = 0.5 * b * h * length b is the length of the triangle’s base. The most basic two equations are as followed: The formulas behind a triangular prism The volume and surface area – these are typically what need calculating when a triangular prism is concerned. There are other prism types such as a rectangular prism. Keep in mind that, via the ‘triangular prism’ term, we’re describing a right triangular prism. Ěcross its whole length, it has an identical cross section.These are oblique prisms and right prisms respectively. Is either in a parallelogram shape or three rectangular faces.What is a triangular prism? To break it down, a prism is a solid object which: If you’re wondering about the formulas behind our triangular prism calculator, read on for further information.
