How many discs would you have to throw into the Lake at Winthrop to raise the water level 1 inch?
(I hope several of you work it out before looking at ANY of the spoilers. p.s. I didn't actually measure the volume of a disc....do it all with assumptions and known tech standards.)

Multiple choice:
A) 17
B) 1,700
C) 170,000
D) 17,000,000
B) 1,700
C) 170,000
D) 17,000,000
Assumptions:
Disc: Flight plate, excluding rim, is 17.3cm diameter and 1.5mm thick. Rim is a 1.5cm equilateral triangle that is 19.2cm long (19.2 is average of outside diameter of 21.1cm and inside diameter of 17.3cm).
Lake: 37,905 square meters minus 1,020 square meters for the island, with vertical walls at the shore, and is entirely enclosed.
Lake: 37,905 square meters minus 1,020 square meters for the island, with vertical walls at the shore, and is entirely enclosed.
Answer:
D) ~17 million discs

It's Friday, I might have messed up the math. The 1.5mm flight-plate thickness is a guess, but hopefully gets us within a couple orders of magnitude. Corrections are welcomed, as are challenges to any of the assumptions.
