Genesis records that the Ark was 300 cubits x 50 cubits x 30 cubits. A cubit is the length from one’s elbow to the tip of their finger. Traditionally this is accepted to be 18”. However, up to a 22” cubit is accepted by Jewish Historians and being 600 years old, Noah’s could have been even bigger!
Accepting the smallest size for a cubit, the Ark would thus be 450’ x 75’ x 45’. This would give the Ark 1,518,750 cubic feet of room. Equal to the capacity of 565 railroad stock cars! But was that enough? To answer this question, we must know how many animals were on the Ark.
Genesis records each “kind” of animal was on the Ark. Though we do not have a list of God’s classification of ‘kinds’, in the creation account, we see that kinds can reproduce. Bearing this in mind, we can see not every ‘species’ was required, but a far smaller number would be required. For instance there would not be a Poodle, Labrador, Great Dane, Wolf and fox on board, but one dog kind.
It is believed this number to be less than 35,000 animals. However, even if we were to take the worst case, and look at species, is there enough room?
Looking even at species, there are only 21,100 species that would have needed the protection of the ark. Multiply this by 2 so we have a male and female of each brings our total to 42,200. There are well less than 1000 ‘clean’ kinds but even adding 7 of each at that many, still leaves the number at less than 50,000 even after adding in two of each dinosaur kind. But will they fit?
If you take all animals, including dinosaurs, from the smallest to the largest, the average size would be that of a sheep. As stated earlier, the Ark can hold the same as 565 railroad stock cars. Shipping records show a stock car will hold 240 sheep. So:
50,000 animals at 240 per car = 208 stock cars. Only 36% of the Ark’s capacity to fit all the SPECIES! Room with plenty to spare!
