Answer: The state government does not own all the land within its borders.
Step-by-step explanation:
The State Government of Arizona does not own all the land within its borders as some land is owned by the Federal Government, others by Native American tribes such as the Cocopah Tribe and the rest (apart from state land) are private.
The Federal Government is said to own more than 26 million acres of Arizona land including land going to the US Forest Service and the Department of Defence amongst others. The Native American tribes own about 19 million acres.
