For example, line 57 in Gilgamesh XI is usually translated (with reference to the boat) "ten rods the height of her sides", or "its walls were each 10 times 12 cubits in height". A rod was a dozen cubits, and a Sumerian cubit was about 20 inches. Hence these translations imply that the boat was about 200 feet high, which would be impractical with the technology in Gilgamesh's time (about 2700 BC). There is no Akkadian word for "height" in line 57. The sentence literally reads "Ten dozen-cubits each I-raised its-walls." A similar example from an unrelated house building tablet reads: "he shall build the wall the house and raise it four ninda and two cubits." This measurement (about 83 feet) means wall length not height.
