摘要

Denote by H a regular hexagon with sides of length 1. Let S be a square with a side parallel to a side of H and let \(\{S_{n}\}\) { S n } be a collection of the homothetic copies of S. In this note a tight lower bound of the sum of the areas of squares from \(\{S_{n}\}\) { S n } that can parallel cover H is determined.
