You can't tell just from this.  The answer is based on the data in the table.  So, if column F is always length 1, the average row length will be different than if it is always 20.  Luckily, Oracle will tell us the answer.

First do:

analyze table mytable compute statistics;


select avg_row_len from user_tables where table_name = 'MYTABLE';
