How many books can you store in 1 GB hard drive?
As explained in my previous post Few rules of thumb
Let’s apply Rule #7 to this problem. As the rule says, “A character is represented by 8 bits” i.e. each character takes about 8 bits. Please note that this problem can be solved only by making few assumptions and your solution depends on the kind of assumptions you make.
Let’s solve the problem now:
- we know 1 byte = 8 bits (Ref. table at the end of this post)
- 1 GB (giga byte) = 1073741824 bytes (≈ 109 bytes) [read it as, 10 power 9]
- 1 GB = 8 * 109 bits
- Now assume on an average every word is comprised of 5 characters
- Assume every page has about 10 lines and each line has about 20 words => 200 words per page
- Number of characters in each page => 5*200 = 1000 characters per page
- Assume every book has about 300 pages => 1000*300 = 300000 characters per book
- Now that every book has about 300,000 characters. The amount of memory taken by each book is
- 300,000 * 8 = 2400000 bits (≈24*105 bits of space)
- The above principle states that each book takes about 24*105 bits of space
- Now, how many bookscan be stored in 1 GB hard drive?
- (8 * 109 )/ (24*105) ≈ 3333.33 books (It’s corrected now. Thanks to the comments)
Answer to the question is… In 1 GB hard drive you can store about 3334 books with the kind of assumptions we made!
We used following conversions to solve the above problem:
- 1 Byte = 8 Bit
- 1 Kilobyte = 1024 Bytes
- 1 Megabyte = 1048576 Bytes
- 1 Gigabyte = 1073741824 Bytes
Your answer should be 3333.3 books
Your calulation is mistaked

Yes I agree with Pramod. A Google search of “(8 * 10^9 ) / (24*10^5)” confirms it that you would be able to store 3333.3 books instead of 333.3.

I agree the calculation is wrong and so is your spelling, lol, Sorry I can’t help it , I am a grammar Nazi.

Then you shouldn’t have capitalised the ‘S’ in the word ‘sorry’ you dullard. And it should have been a semi-colon after ‘….help it’. There should be a semi-colon after ‘agree’. Basically, you’re kind of messed up for a grammar Nazi.

The assumption that “every page has about 10 lines and each line has about 20 words => 200 words per page,” is way off. I just looked at a few trade paperbacks (the larger size) and they averaged about 36 lines a page.
