step 2. NUMBER OF ROWS IN BLOCK.

I think what he wants to do is find out how big a row could possibly be,
for example
CREATE TABLE mytable (
column1 VARCHAR2(40),
column2 VARCHAR2(30),
column3 VARCHAR2 (20));
select table_name, sum(data_length) from user_tab_columns group by
table_name;
TABLE_NAME
