求四棱锥表面积的程序

给定四棱锥的底长(b)和斜高(s) 。任务是找到方形金字塔的表面积。具有方形底部、4 个三角形面和一个顶点的金字塔是方形金字塔。

在这个图中，
b -的正方棱锥的碱基长度。
的S -方形金字塔的倾斜高度。
h——四棱锥的高度。
例子：

Input: b = 3, s = 4
Output: 33

Input: b = 4, s = 5
Output: 56

计算表面的公式是具有(b)底长和(s)斜高的四方锥体。

    $$$ surface\ area (A) = 2 \times b \times s + b^{2} $$$

下面是使用上述公式的实现：

C++

// CPP program to find the surface area
// Of Square pyramid
#include 
using namespace std;
 
// function to find the surface area
int surfaceArea(int b, int s)
{
 
    return 2 * b * s + pow(b, 2);
}
 
// Driver program
int main()
{
    int b = 3, s = 4;
 
    // surface area of the square pyramid
    cout << surfaceArea(b, s) << endl;
    return 0;
}

Java

// Java program to find the surface area
// Of Square pyramid
 
import java.io.*;
 
class GFG {
 
 
// function to find the surface area
static int surfaceArea(int b, int s)
{
 
    return 2 * b * s + (int)Math.pow(b, 2);
}
 
// Driver program
 
 
    public static void main (String[] args) {
         
    int b = 3, s = 4;
 
    // surface area of the square pyramid
    System.out.println( surfaceArea(b, s));
    }
}

Python 3

# Python 3 program to find the
# surface area Of Square pyramid
 
# function to find the surface area
def surfaceArea(b, s):
 
    return 2 * b * s + pow(b, 2)
 
# Driver Code
if __name__ == "__main__":
    b = 3
    s = 4
 
    # surface area of the square pyramid
    print(surfaceArea(b, s))

C#

// C# program to find the surface
// area Of Square pyramid
using System;
 
class GFG
{
 
// function to find the surface area
static int surfaceArea(int b, int s)
{
 
    return 2 * b * s + (int)Math.Pow(b, 2);
}
 
// Driver Code
public static void Main ()
{
    int b = 3, s = 4;
     
    // surface area of the square pyramid
    Console.WriteLine(surfaceArea(b, s));
}
}

Javascript

// javascript program to find the surface area
// Of Square pyramid
 
// function to find the surface area
function surfaceArea(b , s)
{
    return 2 * b * s + parseInt(Math.pow(b, 2));
}
 
// Driver program
var b = 3, s = 4;
 
// surface area of the square pyramid
document.write( surfaceArea(b, s));
