Final answer:
To find the number of acres that are not federally owned out of a total of 4187 million acres, multiply the total by 0.46 to find the federally owned acres. Then subtract the federally owned acres from the total to find the acres that are not federally owned.
Step-by-step explanation:
To find the number of acres that are not federally owned, we need to subtract the federally owned land from the total land. Given that approximately 46% of the land is federally owned, we can calculate the number of federally owned acres by multiplying 4187 million acres by 0.46. This gives us approximately 1923.02 million acres that are federally owned.
To find the number of acres that are not federally owned, we subtract the federally owned acres from the total acres: 4187 million acres - 1923.02 million acres = 2263.98 million acres. Therefore, approximately 2263.98 million acres are not federally owned.
