Program/Source Code:
The source code to calculate the area of Cube is given below. The given program is compiled and executed successfully.
Output:
Explanation:
In the above program, we created two variables side and area, that are initialized with 0.0. Then we read the side of Cube from the user and calculated the area of Cube using the standard formula. After that, we printed the result.
