Programa para calcular area y volumen de un Tetraedro

Complejidad del tiempo: O(1)

complejidad del espacio: O(1)Un tetraedro es simplemente una pirámide con una base triangular. Es un objeto sólido con cuatro caras triangulares, tres en los lados o caras laterales, una en el fondo o la base y cuatro vértices o esquinas. Si las caras son todos triángulos equiláteros congruentes, entonces el tetraedro se llama regular.
 

El área del tetraedro se puede encontrar usando la fórmula: 

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

Ejemplos:  

Input : side = 3
Output : 15.5885

Input : side = 20
Output : 692.82

El volumen del tetraedro se puede encontrar utilizando la siguiente fórmula:
 

Volumen = a ³ /(6√2)

Ejemplos: 

Input : side = 3
Output : 3.18


Input : side = 20
Output : 942.81

// C++ code to find the volume of a tetrahedron
#include <bits/stdc++.h>
using namespace std;
 
// Function to calculate volume
double vol_tetra(int side)
{
    double volume = (pow(side, 3) /
                    (6 * sqrt(2)));
    return volume;
}
 
// Driver code
int main()
{
    int side = 3;
    double vol = vol_tetra(side);
    vol = (double)round(vol * 100) / 100;
    cout << vol;
