20: Cranberry Pyramid

How many cans in the pyramid?


Is this the most stable stacking arrangement?

  1. The pyramid has 80 cans (bottom is 6*6, 2nd layer is 5*5, 3rd layer 4*4 and top 3 cans). As for stacking it, I'd be inclined not to have a pyramid, but make a base of 5*4 cans and stack 3 more on each. The base of each cans tend to have groves for the cans to fit in.

  2. The cans are in hexagonal dense-pack, each layer is triangular in shape. Total is not 80.

  3. Is it 3 + 10 + 15 + 21 = 49 cans?
