Genesis 6:15
Swete's Septuagint · Berean Standard Bible
καὶ οὕτως ποιήσεις τὴν κιβωτόν· τριακοσίων πήχεων τὸ μῆκος τῆς κιβωτοῦ, καὶ πεντήκοντα πήχεων τὸ πλάτος, καὶ τριάκοντα πήχεων τὸ ὕψος αὐτῆς.
And this is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide, and 30 cubits high (note: The ark was approximately 450 feet long, 75 feet wide, and 45 feet high (137.2 meters long, 22.9 meters wide, and 13.7 meters high).).
