The number of btus that are needed to cool lucia’s apartment is 20,400 btus.
<h3>BTUs needed</h3>
First step
Left side=12×10×20
Left side=2400 cubic feet
Middle =16×10×(20-9)
Middle =16×10×11
Middle =1,760 cubic feet
Right side=20×10×20
Right side= 4000 cubic feet
Second step
BTUs:
BTUs=(2400+1760+4000)×2.5
BTUs=8160×2.5
BTUs=20,400 Btus
Therefore the number of btus that are needed to cool lucia’s apartment is 20,400 btus.

The sample space of the experiment is the elements in the set
The sample space {Head, Tail} and there are 2 outcomes in the sample space
<h3>How to determine the sample space?</h3>
From the complete question, the experiment is a toss of a coin
A coin has a head and a tail.
So, the sample space (S) is:
S= {Head, Tail}
The number of outcomes in the above sample space is 2
Hence, the sample space {Head, Tail} and there are 2 outcomes in the sample space
