how many years did noah finished his ARC??

Answer 1

According to the Book of Jasher (referenced in Samuel) it took him 5 years.

I could have that number wrong...read it awhile ago

Answer 2

In Genesis 6:3, God states that he is going to limit human existence to only another 120 years. It is shortly after that (verses 13-21) that God calls Noah to build the ark. So it is often interpreted to mean that Noah had 120 years to complete the building of the ark, collect animals, lay in food, etc. But whether God called Noah immediately after he declared the 120 year limit, or at some point years down the road is not specifically stated.

Answer 3

With only four men working on it, it could have taken from 60 to 80 years.
In size the ark was 300 cubits long, 50 cubits wide, and 30 cubits high. Conservatively calculating the cubit as 44.5 cm (17.5 in.) (some think the ancient cubit was nearer 56 or 61 cm), the ark measured 133.5 m by 22.3 m by 13.4 m (437 ft 6 in. × 72 ft 11 in. × 43 ft 9 in.), less than half the length of the ocean liner Queen Elizabeth 2. This proportion of length to width (6 to 1) is used by modern naval architects. This gave the ark approximately 40,000 cu m (1,400,000 cu ft) in gross volume. It is estimated that such a vessel would have a displacement nearly equal to that of the mighty 269-m (883 ft) Titanic of this 20th century. No cargo vessel of ancient times even slightly resembled the ark in its colossal size. Internally strengthened by adding two floors, the three decks thus provided gave a total of about 8,900 sq m (96,000 sq ft) of space.

Answer 4

I would imagine that Noah finished his ark during the year that it was completed in, so the answer is one. I have no idea how many years it would have taken him to reach that year but being a fictional character it doesn't matter.

Answer 5

It took a long time. Protractors hadn't been invented yet.
