Leibniz` Ge(o)heimnisse: Goldener Keks

Solving the initial puzzle leads you to a driveway. There, you must answer the following three questions: A) How many cookie boxes is the boy carrying as he climbs over the house? B) How many teeth does the famous golden cookie have? C) What is the sum of the letter values of the top letters on the tall chimney?  The final location is then calculated using the formula: N 52 23.(7*A+10*C)E 009 45.(4*(A+B+C)-8). The lock code for the cache is 1646. Inside the cache itself, there is a compartment for trade items with the same code.

Attention: The cache isn't located at the point shown on the map! To find the cache's location, first convert the binary numbers into coordinates. Leibniz would have loved that!
