# Hypercube point picking - unsolved?

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. –  Electro May 28 '12 at 16:13

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.
Although one knows the asymptotics when the dimension $n\to\infty$, which is $\sqrt{n/3}$. –  Did May 28 '12 at 16:18
