计算四面体面积的程序

四面体只是具有三角形底面的金字塔。它是一个具有四个三角形面，三个侧面或侧面，一个在底部或底部以及四个顶点或拐角的固体对象。如果面都是全等边三角形，则将四面体称为正则面。
四面体的面积可以使用以下公式找到：

Area = sqrt(3)*(side*side)

例子 ：

Input : side = 3
Output : 15.5885

Input : side = 20
Output : 692.82

using namespace std;
  
//Utility Function
double area_of_tetrahedron(int side)
{
    return (sqrt(3)*(side*side));
}
 
//Driver Code
int main()
{
    int side=3;
    cout<< "Area of Tetrahedron ="
        << area_of_tetrahedron(side);
}

另一种方法：
四面体的体积可通过以下公式求出：

Volume = a³/(6√2)

例子 ：

Input : side = 3
Output : 3.18


Input : side = 20
Output : 942.81

Java

// java program to find the volume of a tetrahedron
 
import java.io.*;
 
class GFG {
 
// 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);
    System.out.println( vol);
    }
}
