Was the ark large enough to hold all the required animals?
The Ark measured 300 × 50 × 30 cubits ( Genesis 6:15 ), which is about 140 × 23 × 13.5 metres or 459 × 75 × 44 feet, so its volume was 43,500 m³ (cubic metres) or 1.54 million cubic feet. To put this in perspective, this is the equivalent carrying capacity of 340 semitrailer trucks (i.e.
The Ark would probably have carried compressed and dried foodstuffs, and probably a lot of concentrated food. Perhaps Noah fed the cattle mainly on grain, plus some hay for fibre. Woodmorappe calculated that the volume of foodstuffs would have been only about 15 % of the Ark’s total volume.
It is doubtful whether the humans had to clean the cages every morning. Possibly they had sloped floors or slatted cages, where the manure could fall away from the animals and be flushed away (plenty of water around!) or destroyed by vermicomposting (composting by worms) which would also provide earthworms as a food source.
The space, feeding and excretory requirements were adequate even if the animals had normal day/night sleeping cycles. But hibernation is a possibility which would reduce these requirements even more. It is true that the Bible does not mention it, but it does not rule it out either.
This article has shown that the Bible can be trusted on testable matters like Noah’s Ark. Many Christians believe that the Bible can only be trusted on matters of faith and morals, not scientific matters.
