Program to find the surface area of the square pyramid

Given the base length(b) and slant height(s) of the square pyramid. The task is to find the surface area of the Square Pyramid. A Pyramid with a square base, 4 triangular faces, and an apex is a square pyramid.

In this figure, 
b – base length of the square pyramid. 
s – slant height of the square pyramid. 
h – height of the square pyramid.
Examples:

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

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

Formula for calculating the surface are of the square pyramid with (b) base length and (s) slant height. 

Below is the implementation using the above formula: 

C++

// CPP program to find the surface area
// Of Square pyramid
#include <bits/stdc++.h>
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));
    }
}
