How do you picture dimensions?

[wolram]

You have a box obviously it is three dimensional but hollow, using dimensions how
would you turn this box into a solid object?

The top, bottom, ends and sides of the box two dimensional.

Take a two dimensional box cutter, and cut along all the edges. Then place all parts on top of each other.
