ephemerance is correct, here is the ruling,
202.3. The converted mana cost of an object is a number equal to the total amount of mana in its mana cost, regardless of color.
Example: A mana cost of {3}{U}{U} translates to a converted mana cost of 5.
Trinsphere forces you to pay at least 3 but does not change the mana cost
202.4. Any additional cost listed in an object’s rules text or imposed by an effect isn’t part of the mana cost. (See rule 601, “Casting Spells.”) Such costs are paid at the same time as the spell’s other costs.
