OP here again
I've worked out the simplest case of a 4d iron cube packed the same as a 3d cube.
The width of a metallic iron atom is 126 picometres, so in an extra spacial dimension, you could fit 793.7 million iron atoms across 10cm assuming it has the same 4d diameter.
This means it would weigh about 6.2 billion kg.
