It depends on how deep the cake pan is.
6 cups for one layer
For a 12x12x3-inch cake pan, you'll need approximately 9 to 10 cups of cake batter. This is based on the volume of the pan, which is about 432 cubic inches. Depending on the recipe and the density of the batter, adjusting slightly may be necessary, but this amount should fill the pan adequately without overflowing.
10-12 cups of batter
The number of boxes of cake mix needed depends on the size of your cake pans. Generally, one box of cake mix makes about 4 to 5 cups of batter, which is sufficient for a 9-inch round or square pan. For larger pans, such as 12-inch or 10-inch rounds, you may need 2 boxes, while for a 9x13-inch pan, one box is usually adequate. Always check the specific instructions on the cake mix box for the best results.

How deep is the pan? 2" or 3"? It makes a huge difference.
One does not bake cake pans. Cake batter is poured into cake pans and then the cake is baked in the pan. A cake in a 10" pan is baked like any other cake, in a moderately hot oven (325 - 350 degrees F) until it tests done. Because the batter in the center of a 10" pan takes longer to bake than the batter nearer to the edge, it can be helpful to use the lower range of suggested temperatures. Another useful hint is to tie a dampened rag around the outer edge of the cake pan. This keeps the outer edge slightly cooler and allows the cake batter to heat more evenly throughout.

To bake a perfect cake in a glass bundt pan, make sure to properly grease and flour the pan to prevent sticking. Allow the cake to cool in the pan for 10-15 minutes before flipping it onto a wire rack to cool completely. Follow the recipe instructions carefully and avoid overmixing the batter to prevent a tough cake. Lastly, monitor the baking time closely and use a toothpick to check for doneness before removing the cake from the oven.
There are 11 cups of batter in an 11x15 pan for a 2 inch layer. I would guess for an 11x13, maybe 10 cups?
There are many ways to do so. To ensure easy removal, you should be sure to prep the cake pan before you pour the cake batter in to bake. You can do this by using a butter-and-flour technique, buttering the pan, or by using a non-stick baking spray. After the cake is done baking, let it rest for about 10 to 15 minutes (longer if it is a larger-than-average sized cake) on a cooling rack or elevated area (so that air can flow all around and underneath the cake pan). You can run a butter knife along the edge of the cake and pan to loosen the edges. Gently flip the cake over onto a flat, cool surface or a drying rack and the cake should emerge easily and cleanly.
