Got ya, sorry I should have explained better. I meant 1/2" each side by whatever length the spud is. To us Brits that's 1/2" square, if it was 1/2" X 1/2" X 1/2", that would be a cubeI know, but you said, "Imagine a chip 1/2" square..." I imagine a square/cube/rectangle as having 6 sides; if it only had 4 sides it would be 2-dimentional and would belong in the realm of science fiction.
