An activation cost of {X}{X} means that you pay twice X. If you want X to be 3, you pay {6} to activate Blast Zone's ability.

If a permanent has {X} in its mana cost, X is considered to be 0.

Tokens that aren't a copy of something else don't have a mana cost. Anything without a mana cost normally has a mana value of 0.
