divide 5 billion by $5,$ to get the total number of words. $5,000,000,000 / 5=1,000,000,000$ words. Then divide this by $300,$ to get the number of pages. $1,000,000,000 / 300 \approx 3,333,333$ pages. And finally, divide that by 300 to get the length of shelf space. $3,333,333 / 300=11,111.11$ inches which is about 926 feet.
