In size the ark was 300 cubits long, 50 cubits wide, and 30 cubits high.(Gen 6:15) What is that in footage and/or metric?

Bonus: What is the gross volume of the ark in cu. ft. and/or cu. meters?

"Noah's Ark was taller than a 3-story building and had a deck area the size of 36 lawn tennis courts. Its length was 300 cubits (450 feet, or 135 meters); its width was 50 cubits (75 feet, or 22.5 meters); it had three stories and its height was 30 cubits (45 feet, or 13.5 meters)."

That's a quote from a web page. Go to google.com and search. You'll find lots of info.

450 ft long, 75 ft wide, 45 ft high

It would have 1,518,000 cuic feet in volume

Good Job guy's here are some numbers I have.

*** it-1 p. 164 Ark ***

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 the 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
