Declare and initialize the variable named “fact” and store the calculated area value in it.

Initialize a for loop which ranges from 1 to -1

Add the value of factor to fact.

Return the value stored in the “fact” variable.

The function named “sumNCubes()” is defined and inside the “sumNCubes()”,

Declare and initialize the variable named “cube” and store the calculated area value in it.
