   [A HOLLOW CUBE] Holes

Does this mean that we can watch through the other side through the hole ? or its just one set of unit cube which is missing ?

peridream - August 10, 2016 - 20:20
   [A HOLLOW CUBE] Question

I assume that the holes of the cube go through the whole cube.

So the depth of the holes IS NOT only one layer.

euklid - August 10, 2016 - 19:10
   [A HOLLOW CUBE] Clarification request

It is not clear whether the hole is only in the 6 faces (the interior of the cube being full) or the holes go through the whole cube (i.e. the figure represents what one can see when one looks at any face of the cube, and one needs to find the maximum number of sticks).

   [A HOLLOW CUBE] Question

What is two-cubed shape. Can you draw it?

zel47 - August 10, 2016 - 12:28
   Numbered Balls

Nice, but I think it would have been much better, if you had asked for the exact probability.

Dandelo - August 05, 2016 - 08:59
   [NUMBERED BALLS] brilliant

thats quite a challanging one. tx

allanc - August 04, 2016 - 07:11
