Answer

500,000 rows Explanation 1. Understand Cartesian Product The Cartesian product of two tables results in a table where each row from the first table is combined with every row from the second table. 2. Calculate Total Rows Multiply the number of rows in the customer table by the number of rows in the invoice table. **Total Rows = 1000 \times 500**.
