World's Largest Hollow Diagonal Cube (Zen Magnets)

In this video, I show how to build a giant hollow diagonal cube out of Zen Magnets. The cube has triple-thickness walls, edge count 23, and 17,451 magnets. It weighs 19 pounds and is very strong. As far as I know, it is the largest and heaviest hollow diagonal cube that has ever been built. The technique is an extension of Mathnetism’s technique for building hollow cubes with double-thickness walls (see    • Hollow Diagonal Cube (Zen Magnets)  ,    • TUTORIAL Hollow Diagonal Cube (Zen Magnets)  , and    • Mathnetism's Hollow Diagonal Cube (Zen Mag...  ). The number of magnets required for a hollow diagonal cube with triple thickness walls is given by N = 36n^2 - 72n + 63, for edge count n = 3 and larger. This gives: n, N 3, 171 4, 351 5, 603 6, 927 7, 1323 8, 1791 9, 2331 10, 2943 11, 3627 12, 4383 13, 5211 14, 6111 15, 7083 16, 8127 17, 9243 18, 10431 19, 11691 20, 13023 21, 14427 22, 15903 23, 17451 24, 19071 25, 20763 26, 22527 27, 24363 28, 26271 29, 28251 30, 30303 31, 32427 32, 34623 33, 36891 34, 39231 35, 41643 36, 44127 37, 46683 38, 49311 39, 52011 40, 54783 41, 57627 42, 60543 43, 63531 44, 66591 45, 69723 46, 72927 47, 76203 48, 79551 49, 82971 50, 86463
