If 56% of the land in the state is federally owned, that means 44% of the land is not federally owned.
To find the number of acres that are not federally owned, we can use the following formula:
(percent not federally owned/100) x total acres = non-federally owned acres
(44/100) x 2051 = 908.44 million acres
So, approximately 908.44 million acres of land in the state are not federally owned.
