16 : C Program to Calculate Surface area of Cube

Check out the complete list of c-programs : C Program List

To calculate surface area of cube you need to know the side of the cube

Variables :

1. side : (Datatype int) : to represent the side of cube.

2. surface_area_of_cube : (Datatype long) : to store volume of Surface area of cube.

Functions :

printf() : is used to display something on the console/screen. Format specifier %d in printf function is used to display a int variable on screen and %f for float. \n is used to add a newline

scanf() : is used to fetch data inputted by the user on the console/screen using keyboard. %d in scanf is indicates that inputted text is of type int and %f for float.

Formula :

Surface Area of a Cube : 6 x side3

• Output :

Program to calculate Volume of a Ellipsoid :

Enter the Radius 1 of Ellipsoid : 2

Enter the Radius 2 of Ellipsoid : 4

Enter the Radius 3 of Ellipsoid : 6

Volume of Ellipsoid with (r1,r2,r3) as (2,4,6) = 150.815994
