Problem M19a on p58 and p71 (in "The mathemagician and pied puzzler" by Elwyn Berlekamp and Tom Rogers) ask for the point further away (on the surface) from a corner of a 1x1x2 dicube. The given answer is not the opposite corner. Is this an error?

Indeed. Looks like an error.
The left one corresponds to the ant first crawling over the bottom 1×1. Here indeed P is father away than B. In the second, the ant starts over the side surface. In this case B is certainly father than P. Comparing the distances in the two cases P is nearer to A than B.
