C++ Program to Find Curved Surface Area of a Cube

A cube is a 3-dimensional box-like figure represented in the 3-dimensional plane. Cube has 6 squared-shape equal faces. Each face meets another face at 90 degrees each. Three sides of the cube meet at the same vertex. The curved surface area of a cube is the sum of the areas of all its faces, except its top and bottom faces. Hence, the curved surface area of the cube is the sum of areas of all four side faces of a cube.

Input: Side of the cube =2

Output: Curved Surface area = 16

Curved Surface Area of a cube is: 4 * a * a

where, a is the side of the cube

C++

// C++ program to find area
// curved surface area of a cube
#include <bits/stdc++.h>
using namespace std;

// utility function
double CurvedareaCube(double a)
{
    return (4 * a * a);
}
// driver function
int main()
{
    double a = 2;
    cout << "Curved surface area = " << CurvedareaCube(a);
    return 0;
}

Output

Curved surface area = 16

Time Complexity: O(1)

Auxiliary Space: O(1)
