In Star Trek: The Original Series Season 2, Episode 15, "The Trouble with Tribbles," the crew of the USS Enterprise is summoned to protect a disputed planet, Sherman's Planet, which is crucial under a treaty between the Federation and the Klingon Empire. While on shore leave at a space station, Lt. Uhura brings aboard a small, adorable creature called a tribble. These tribbles reproduce rapidly and seem to love everyone—except Klingons, whom they instinctively dislike. As their population explodes, Spock calculates the population to be a staggering 1,771,561 tribbles (That's assuming one Tribble, multiplying with an average litter of ten, producing a new generation every 12 hours, over a period of three days).

In a comedic climax, Captain Kirk opens a storage container to check on the status of the grain, then he is buried under an avalanche of tribbles that had infiltrated the area, much to his chagrin. The tribbles ultimately help the crew uncover a Klingon plot to sabotage the Federation's grain supply.

To solve for the final, take the square root of Spock's calculation, divide it by 1000 and add it to both of the follow coordinates: N 42° 09.531′ W 93° 49.168′. Again, the cache is not at the posted coordinates and it is not these coordinates. You must use a bit of math to solve for the final.
