Most refrigerators contain multiple trays for storing eggs. Another thing is really interesting. In most models, these trays are divided into 8 cells. Given this feature, it can be logical to assume that the case concerns a certain "standard". Well, it's time to find out why most trays in refrigerators are designed according to this formula.
An interesting discrepancy - eggs are sold in dozens, but the trays in most refrigerators are divided into eight cells. It looks at least strange, if (of course) pay attention to this issue. If you want, you can even go and count the number of cells in the egg trays of your refrigerator right now. Most likely there will be eight of them. Why is this so? The answer is actually very simple and it boils down to two words "European" and "standard".
The fact is that in European countries, eggs are usually sold not in dozens, but in packs, one way or another related to a dozen - 12. They sell chicken eggs in 12, 6, but much more often in 8 pieces. It is for this reason that there are eight cells in most refrigerator models. They are just designed for the most popular store containers. No less curious is the fact that trays for 8 have quite a long history.

The fact is that even 50-70 years ago eggs in many European countries were sold in six pieces. This was primarily due to the fact that agriculture at that time did not allow the production of chicken eggs in the volumes in which they are produced by modern farms. Over time, the situation began to change and there were 8 eggs in the trays. The number turned out to be optimal (from the point of view of Europeans), and so it stuck.

Separately, it should be noted that, unlike people from the east, people from the west, primarily Europeans, are much more inclined to “think in dozens”, and not in 10 or 3. The magic of numbers is obvious: 12 months, 12 apostles, 12 zodiacal signs, etc. Even the A4 sheet size is 1/3 of that same dozen.
