Abstract
What is the least surface area of a shape that tiles R d under translations by Z d ? Any such shape must
have volume 1 and hence surface area at least that of the volume­1 ball,
namely# # d). Our main result is
a construction with surface area O( # d), matching the lower bound up to a constant factor of 2 p 2#/e # 3.
The best previous tile known was only slightly better than the cube, having surface area on the order of d.
