Hey friends, I am a newbie here, was just thinking about a challenging problem.decided to come here and ask you guys about it, Hope you could help me, Here is my question:consider two metallic cubes of the same size, lets say 10x10x10 cm.....one of them is quite solid, made from a ferro-metal (for example steel)... but the other one is a hollow cube with an inner space...the cubes seem exactly the same....in the inner space of hollow cube, some non-ferro material is placed (this cube is infilled with a non-ferro material)....no need to mention that non-ferro material is not also visible (it is trapped inside the cube)....when we weigh two cubes they show to have the same weight because the amount of non-ferro material (trapped inside the hollow cube) weighs exactly like if we have filled that space with base material.....SO we have two cubes with the same size, same look and same weight, one of them made from a homogeneous ferro-material and the other one made from two different materials (outer part steel and inside part non-ferro) .....Now here is the question.... How can I investigate which is which in a nondestructive way? (without cutting cubes)thanks friends,Reza
