* Is a 9x13 inch cake pan the same as a rectangular cake pan? Yes, it's a very common size for rectangular cake pans.

* Is a 9x13 inch cake pan the same as a 9x13 inch baking pan? Essentially yes. The terms are often used interchangeably, but a "baking pan" is a broader term that could include other shapes like round or square.

The important thing is to know the exact dimensions when you're looking for a specific pan. Always double-check the size before you buy!
