None, since there can be no conversion.
A cubit equals 1.5 feet so a cubit foot equals 1.5 square feet which is a measure of area in 2-dimensional space. The amount of air breathed requires a measure of volume in 3-dimensional space. The two measures are different and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
1 cubit = 1.5 feet so 1 cubit feet is an area of 1.5 square feet.
1 cubit = 1.5 feet so 1 cubit foot is an area of 1.5 square feet.
1 cubit = 1.5 feet so 27 cubit feet is an area of 40.5 square feet.
There are 3 cubit feet in 1 cubit yard. Although irrelevant in this context, you may wish to know that 1 cubit = 1.5 feet = 0.5 yards.
1 cubit = 1.5 frrt so 1.5 cubit feet = 2.25 square feet.
8 cubit feet = 12 square feet.
288 cubic feet of "air" or 19 cubic feet of pure oxygen .
Formula: Noah cubit x 1.6916 = feet300 cubits = about 507.5 feet
Plywood is usually sold in sheets with an area of approx 32 cubit-feet.
1 cubit = 1.5 feet
A cubit = 1.5 feet so a cubit foot is a measure of area in 2-dimensional space. There is no measure of volume and therefore there is no value which can be assigned.
512 feet squared
