There is an article at https://www.chabad.org/parshah/article_cdo/aid/3514607/jewish/Torah-and-Mathematics-The-Secret-of-Noahs-Ark.htm that makes some interesting points about the possibly triangular and pyramid-like shape of Noah’s Ark, and its relationship to the pyramids of Egypt. (Also in the article are other interesting ideas including about the concepts of One and Zero.) Here is an excerpt of the text pertaining to the Ark (to see the figures please see the cited link): The L rd clearly instructed Noah about the exact spatial dimensions of the Ark: “This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high. You shall make a (tzohar) window for the ark, and narrow it to a cubit at the top”. The picture below shows how this appears in geometerical terms. Figure 1. Geometry of the ArkFigure 1 shows that the Ark was shaped like a truncated pyramid. The angle of elevation at its side equals 50.76°. The angle of elevation of the Great Pyramid of Giza is 51.52°. The angle of elevation of the Pyramid of Khafre is 52.2°. The angle of elevation of the Pyramid of Menkaure is 50.47°. Thus, it is obvious that the angle of elevation of the Ark’s side matches the angles of elevation of the three pyramids of Giza within the bounds of observational error. Figure 2. Geometry of the Great Pyramid of GizaBased on what we shared above, we may make the bold supposition and say that the Egyptian Pyramids were constructed in the likeness of Noah’s Ark and they were ‘modelled’ on it. If we divide the sum of width and height of the Ark by its width, i.e. 50 + 30.612/50, the result is 1.612. If we divide the width of the Ark by its height (50/30) the result is approximately 1.667. As for the Great Pyramid of Giza, this ratio is approximately 1.631. The Golden Ratio (φ) is approximately 1.618. Just like π, φ is a universal irrational number in mathematics. In this case, the insignificant deviation of the Ark’s dimensions from φ can be explained by the fact that the L rd instructed Noah only in integers. When the Jews constructed the tabernacle in the Wilderness, G d commanded Moses: “Let them make an Ark [of covenant], of cedar wood, two and a half cubits long, one and a half cubit wide, and one and a half cubit high,” (figure 3). Figure 3If we take ratio (2.5 + 1.5)/2.5 = 1.6If we take ratio 2.5/1.5 = 1.(6) Here the difference between ratios of Ark of Covenant and Golden Section (φ) is due to the fact that G d gave the size of the Ark in integers. The Golden Ratio is a special number found by dividing a line into two parts, so that the longer part divided by the smaller part is in the proportion approximately of 68/32. The first mathematician to study the Golden Ratio was Euclid, who did so around 300 B.C. Euclid demonstrated that the Golden Ratio can be found in various geometric figures. The Golden Ratio was also studied in the Middle Ages, and even today mathematicians continue researching this. The Golden Ratio is often utilized in painting, music and architecture phenomenon. Among those who have studied the Golden Ratio we can name Leonardo of Pisa, astronomer Johannes Kepler, and Roger Penrose. Fibonacci, the great Italian mathematician of the 12th century who brought algebra to Europe, showed that the ratio between any two adjacent numbers in a series named after him (where every following number is the sum of the two preceding ones) tends towards φ. The Golden Ratio is often utilized in painting, music and architecture, and we can often observe it in nature (in the structure of leaves or parts of the human body), as well as on the atomic level. Some researchers compare the Golden Ratio to the structure of the human DNA genome. The fact that we find in Torah a universal mathematical number constitutes irrefutable evidence that the L-rd has written the Law of our universe in a way that it can be also read in mathematical language. It is also not by accident that the Ark was shaped like a truncated pyramid. Some hypotheses (although not yet confirmed academically) say that the space inside a pyramid-shaped structure acquires special properties in terms of energy. Famous Torah commentators have also written about the shape of the Ark. Commenting on Bereshit 6:16Ibn Ezra stated that the Ark was of triangular shape with a sharp vertex and acute angles to prevent it from overturning. Commenting on Bereshit 8:4Ramban said: And what is more: on the seventeenth day of Elul he sent a dove, and there was water all around the earth and the trees were beneath the water. But twelve days passed and everything dried up. We may conclude that if the Ark had eleven cubits beneath the water level (which is more than one third of its height) it should have sunk, as it would be too wide at its bottom part and have just one cubit at its top part. This is not the way one should build a ship, as such a design makes it too heavy. Commenting on Bereshit 6:16Abravanel wrote: the Holy Scripture says that He instructed him to build the Ark in a triangular shape, leaving at the top a length of just one cubit and six cubits wide formed by four beveled facets so that the falling raindrops stream down the walls of the Ark. Thus, we see once more that the Torah contains the fundamental mathematical principles of our universe’s structure. — Until here the quotation. Any remarks about this?
