Hello fellow decorators!

I am new to baking and would like to ask some help regarding cake pans. I have the following cake pans and have no idea how many cups of cake batter is needed to fill them up when baking.

Pan 13 inches x  8 inches x  3 inches deep.

Pan 12 inches  x 7 inches  x 3 inches deep 

Pan 10 inches  x 6 inches   x 3 inches deep.

Lastly, what would be the recommended oven tempretures.

Thank you.   

i suggest that you fill them halfway with water and measure that to get the correct amount -- i bake at 350 f

Excellent, thank you very much for help & for responding -k8memphis. I can now embark on the wonderful journey of cake making and your suggestion has helped a newbie like myself emmensily. 

Thanks again.
