Question

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?

Answer 1

The answer is 6×103
2×10−2. =3×105

Answer 2

Answer:

Dimensions of paperback book :

Length = 12 feet

Breadth = 15 feet

Height = 15 feet

Volume of Paperback book = $Length \times Breadth \times Height$

                                             = $12 \times 15 \times 15$  

                                             = $2700 ft^3$  

Dimensions of swimming pool:

Length = 40 feet

Breadth = 30 feet

Height = 5 feet

Volume of swimming pool = $Length \times Breadth \times Height$

                                             = $40 \times 30 \times 5$  

                                             = $6000 ft^3$  

Now we are supposed to find  how many paperback books would fill the community pool he visits.

So, No. of paperback books would fill the community pool:

=$\frac{\text{Volume of swimming pool}}{\text{Volume of paperback book}}$

=$\frac{6000}{2700}$

=$2.22$

Thus 2 paperback books would fill the community pool
