Eduardo uses the Fermi process and the following estimates to determine how many paperback books would fill the community pool he visits.

A paperback book is about ​ 12 ​ ft long, ​ 15 ​ ft wide, and ​ 15 ​ ft thick.

The swimming pool is about 40 ft long, 30 ft wide, and 5 ft deep.

 

Which equation could he have written?

6×1032×10−2=3×105

6×1032×10−2=3×101

6×1042×10−2=3×106

6×1042×10−2=3×102

Well, I'll answer how many paperbacks he can fit.

Since each paperback is 12ft*15ft*15 ft thick

And, the swimming pool is 40ft*30ft*30ft

We can do:

\(\frac{40*30*5}{12*15*15}=\frac{6000}{2700}=2.22\approx\boxed{2}\)
