Ask HN: Solve this FoundersFund problem

Radius r = 1080 meters.

Volume of a sphere = (4/3) * pi * r^3

Surface area of a sphere = 4 * pi * r^2

We want to find x, some unit of measure.

The volume of the sphere in units of x^3 is:

((4/3) * pi * r^3) / x^3

The surface area of the sphere in units of x^2 is:

(4 * pi * r^2) / x^2

The problem states these are equal. So:

((4/3) * pi * r^3) / x^3 = (4 * pi * r^2) / x^2

(1/3) * r = x

360 = x

nope...try a little harder :)

It's early...

360

correct..now go ahead and submit your business plan :)
