How to Find the Height When Given the Volume of an Equilateral Triangular Prism? 'h' = Height of equilateral triangular prism.The volume of an equilateral triangular prism formula is used to calculate the volume when the side length and height of the equilateral prism are given. What Is Volume of an Equilateral Triangular Prism Formula? Other common units of volume are milliliters and liters. In the metric system of measurement, volume of an equilateral triangular prism is expressed in cubic units, like m 3, in 3, cm 3, ft 3, yd 3, etc. What Units Are Used With the Volume of the Triangular Prism? The volume of an equilateral triangular prism can be easily found out by using the formula, Volume = (√3/4)a 2 × h, where,'a' is side length and 'h' is the height of the equilateral triangular prism. How Do You Find the Volume of an Equilateral Triangular Prism? An equilateral triangular prism is a three-dimensional shape having its bases as equilateral triangles. Volume of the equilateral prism is defined as the total space it covers inside itself. All the other versions may be calculated with our triangular prism calculator.FAQs on Volume of an Equilateral Triangular Prism What Is Meant By Volume of Triangular Prism? 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) Breakdown tough concepts through simple visuals. Show Answer > go to slide go to slide go to slide.
Therefore, the base of the triangle measures 2.5 units. Triangular base: given two angles and a side between them (ASA) By substituting these values in the volume of triangular prism formula, we get, Volume ½ × b × h × l. 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) Triangular base: given two sides and the angle between them (SAS) However, we don't always have the three sides given.
Step 1: Determine the base area and the height of the prism. You can calculate that using trigonometry: Thus, we follow the below steps to find the volume of equilateral triangular prism. 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: The formula for the volume of a triangular prism is given by, V B x h, where B is the base area and h is the height. Length * Triangular base area given triangle base and height 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.
