How do I convert batter from and 8 inch round cake pan to a 10 inch one?

so say I got a recipe for a chocolate cake with a cake mix that has a recipe instruction of:

2 3/4 cups (550 ml) chocolate cake mix

3/4 cups (220) water

3 eggs

3/4 cups (214) veg oil

for enough batter to fill two 8 inch round cake pans, how would I scale it up for a 10 inch round pan?

do I just scale it all up by a quarter, say 3 1/4 cake mix, 1 cup water, 4 eggs, and one cup veg oil?
