Java Program for Program to calculate volume of a Tetrahedron Last Updated : 07 Aug, 2022 Comments Improve Suggest changes Like Article Like Report A Tetrahedron is simply a pyramid with a triangular base. It is a solid object with four triangular faces, three on the sides or lateral faces, one on the bottom of the base and four vertices or corners. If the faces are all congruent equilateral triangles, then the tetrahedron is called regular. The volume of the tetrahedron can be found by using the following formula : Volume = a3/(6√2) Examples : Input : side = 3 Output: 3.18 Input : side = 20 Output: 942.81 Java // Java code to find the volume of a tetrahedron import java.io.*; class Tetrahedron { // Function to calculate volume static double vol_tetra(int side) { double volume = (Math.pow(side, 3) / (6 * Math.sqrt(2))); return volume; } // Driver Code public static void main(String[] args) { int side = 3; double vol = vol_tetra(side); vol = (double)Math.round(vol * 100) / 100; System.out.println(vol); } } Output3.18Time Complexity: O(1) Space Complexity: O(1) Comment More infoAdvertise with us Next Article Java Program for Program to calculate volume of a Tetrahedron K kartik Follow Improve Article Tags : Java area-volume-programs Practice Tags : Java Similar Reads Program to calculate area and volume of a Tetrahedron A Tetrahedron is simply a pyramid with a triangular base.
