Question: My 4th and 5th Grades and I are building a 1/64th scale model of Noah’s Ark. We have done a lot of math on this project. Are there measurements on the design of the ark’s interior? This project was done along with a year-long study of the challenges Noah had in following God’s will.
Answer: In your study of Noah’s life, you must conclude...God made every provision needed for those in the ark...including the size of the "accommodations".
"Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch." (Genesis 6:14).
Verses 15 and 16 of Genesis 6 continue with the rest of the specifications for the ark. Pertinent to your question, the Hebrew word for "rooms" comes from a prime root meaning "to nestle, i.e. build or occupy as a nest." It brings the idea that what God wanted built for "rooms" was the type of place each animal would feel comfortable in. Would a loving God do less? The Bible does not specify dimensions or a description, other than the meaning of the Hebrew word.
Because he believed God’s Word, Noah built the ark; and he and his family entered in, and were saved from the judgment of the flood. By doing this, Hebrews 11:7 tells us he became an "...heir of the righteousness which is by faith." The ark is a picture of our salvation in Christ. The word translated "pitch" in Genesis 6:14, is the same word translated "atonement" in Leviticus 17:11.
It is Christ’s atonement for sin that keeps out the waters of judgment; and makes the believer’s position "in Christ" safe and blessed. If we are "in Christ" we become "heirs of the righteousness which is by faith."
Are you in the Ark of Safety?
"And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:" (Philippians 3:9)
