How much of Alaska did we buy?

Question by Taylor: How much of Alaska did we buy from Russia?
I need to know all these details:
1. How large (in square miles) was the territory purchased from Russia?
2. How much per acre was the final deal worth?
3. How large (in square miles) was the Louisiana Purchase territory?
4. How much per acre was this deal worth?

I know the Louisiana Purchase thing is random but trust me, I just need it.
Any help will be greatly appreciated.
