MathWorld says that picking a random point in a unit $n$-cube is an unsolved problem. Why? Isn't it enough to pick $n$ random numbers uniformly distributed in $[0, 1]$?

    Hm? Why the downvote? I think it's perfectly possible to have been confused by the "Foundations of Mathematics > Mathematical Problems > Unsolved Problems" at the top.2012-05-28

It doesn't say anything like that. It says that there is no known closed-form expression for the expected distance from a random point to a particular vertex of an $n$-cube.

    Ah. So that's why they put it in the "Unsolved Problems" list?2012-05-28

    Although one knows the asymptotics when the dimension $n\to\infty$, which is $\sqrt{n/3}$.2012-05-28
