Do you want to mold a smooth-surfaced right rectangular prism or just a
rough block for further work? If you just want a block mold, visit a
commercial cooking supply store and look for the appropriate size baking pan
or mold. Some bread pans are about the right size and they even have plenty
of draft for unmolding.

If you want a straight-sided block you might be able to find a suitable
plastic storage box in an office or home supply store. It should still have
a wee bit of draft (a good thing) because it had to come out of its mold.
Fill it with sand to help it hold shape while you cast your mold around it.

Hi I was wondering if anyone had any ideas about where to find a
approx. 10" h x 5" w x 4" deep solid cube (no lines) so I can make a
mold of it and cast resins or whatever into it ??

The only thing I could find are some trophy cubes (that are hollow);
these are a pain to try and seal..

Thanks!
