Program for Surface Area of Octahedron

Given the sides of Octahedron then calculate the surface area.

Examples:

Input  : 7
Output : 169.741

Input  : 9
Output : 280.59

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

An regular octahedron has eight faces, which are all in the shape of equilateral triangles.The area of an octahedron is 2 multiplied by the length of an edge squared multiplied by the square root of three.

Formula:
Surface area= 2*(sqrt(3))*(side*side)

C++

 // CPP Program to calculate  // surface area of Octahedron #include using namespace std;    // utility Function double surface_area_octahedron(double side) {     return (2*(sqrt(3))*(side*side)); }    // Driver Function int main() {     double side = 7;     cout << "Surface area of octahedron ="         << surface_area_octahedron(side)         << endl; }

Java
