ANSWER

EXPLANATION
The room represents a rectangular prism or a cuboid.
The dimensions of the room are 30 feet by 16 feet by 8 feet(height).
The volume of a rectangular prism is

Substitute the given values

Simplify:

Hence the cubic feet of air in the room is 3,840ft³.
A perfect number is a number where the sum of its divisors is equal to the number.
For example 6: 1 + 2 + 3 = 6
Another example is 28: 1 + 2 + 4 + 7 + 14 = 28
Here is a short list of perfect numbers: 6, 28, 496, 8128, <span>33550336, and the numbers get way bigger as we go on.</span>
The tables shows that the relative frequencies for each number are very similar 0.19, 0.20 and 0.21.
That drives to tell that the outcomes appear to be equally like.
That means that the probabilities are uniform, so the answer is:
<span>The
outcomes appear to be equally likely, so a uniform probability model is
a good model to repersent the probabilities in Tyra's experiment.</span>
