计算十二面体的体积

原文:https://www . geesforgeks . org/calculate-volume-十二面体/

给定十二面体的边，计算它的体积。体积是形状占据的空间量。 A 十二面体 是一个由 12 个面或平边组成的三维图形。所有的面都是同样大小的五角星。“十二面体”一词来源于希腊语中的“十二面体”和“面”。 公式: 体积= (15 + 7√5)*e 3 /4 其中 e 为一条边的长度。 示例:

Input : side = 4
Output : 490.44

Input : side = 9
Output : 5586.41

C++

// CPP program to calculate
// Volume of dodecahedron
#include <bits/stdc++.h>
using namespace std;

// utility Function
double vol_of_dodecahedron(int side)
{
    return (((15 + (7 * (sqrt(5)))) / 4)
                       * (pow(side, 3))) ;
}
// Driver Function
int main()
{
    int side = 4;

    cout << "Volume of dodecahedron = "
         << vol_of_dodecahedron(side);
}

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to calculate
// Volume of dodecahedron

import java.io.*;

class GFG
{
        // driver function
    public static void main (String[] args)
       {
           int side = 4;
           System.out.print("Volume of dodecahedron = ");
           System.out.println(vol_of_dodecahedron(side));
       }

     static double vol_of_dodecahedron(int side)
        {
             return (((15 + (7 * (Math.sqrt(5)))) / 4)
                       * (Math.pow(side, 3)));
        }
}

<?php
// PHP program to calculate
// Volume of dodecahedron

// utility Function
function vol_of_dodecahedron($side)
{
    return (((15 + (7 * (sqrt(5)))) / 4)
                      * (pow($side, 3))) ;
}

    // Driver Function
    $side = 4;
    echo ("Volume of dodecahedron = ");
    echo(vol_of_dodecahedron($side));

java 描述语言

<script>
// javascript program to calculate
// Volume of dodecahedron

// utility Function
function vol_of_dodecahedron( side)
{
    return (((15 + (7 * (Math.sqrt(5)))) / 4)
                       * (Math.pow(side, 3))) ;
}

// Driver Function
    let side = 4;
    document.write("Volume of dodecahedron = " +
    vol_of_dodecahedron(side).toFixed(2));

    // This code contributed by gauravrajput1
</script>

输出:

Volume of dodecahedron = 490.44
