A solid cube of radium is floating in deep space. Each edge of the cube is 1km in length. An astronaut is protected from its radiation if she remains at least 1km from the nearest spec of radium including the interior of the cube. What is the volume (in cubic km) of space that is forbidden to the astronaut?

We've concluded that:
-The shape can't be a sphere nor a cube
-The shape does not have vertices
-The corners are arced so that she remains exactly 1km from the radium
-The distance from arc to arc is 3km

We have some idea of what it looks like, but do not know how to calculate the volume. Any suggestions would be EXTREMELY helpful. :)

I'm just trying to figure out if most people think the way I do. I say it her birthday is 3 days before. Just wondering if some people would consider it to be 2 days before. I'll wait to reveal her actual birthday.
