How is a Cartesian join calculated in terms of resulting rows?

The Cartesian join, also known as a cross join, results in a combination of every row from one data frame with every row from another data frame. This means that if you have one data frame with a certain number of rows and another data frame with a certain number of rows, the total number of resulting rows from the Cartesian join will be the product of the number of rows in the first data frame multiplied by the number of rows in the second data frame.

For example, if Data Frame 1 has 5 rows and Data Frame 2 has 3 rows, a Cartesian join will result in 5 multiplied by 3, which equals 15 rows in the resulting data set. Therefore, the correct method of calculating the number of resulting rows from a Cartesian join is to multiply the number of rows in the first data frame by the number of rows in the second data frame.
