Answer: sqr 29 m.

Basically you have to find the distance from say bottom left corner to the top right farther corner of a 3D rectangular box...

The simplest way to do this is Distance = sqrt (L^2+w^2+H^2)...

So the distance in this case will be Sqrt (4^2+3^2+2^2) = Sqrt(16+9+4) = sqrt(29)

There is an algebraic way to solve this too but that would need more explanation and more confusion...
