To find a specific number in Pascal's triangle, use the formula n!/r!(n-r)!

Where n is the row number (starting at 0) and r is the row element (starting at 0)

So for the 3rd entry of the 12th row we would put in the following numbers:

11!/2!(11-2)!

which equals 55

Do the same for the 6th entry of the 12th row and you get 462.
