The article, typed on a computer, contains 20 pages, each page has 40 lines, and each line has 48 characters. In one representation of Unicode, each character is encoded as two bytes. Determine the information size of the article in kilobytes in this Unicode representation variant.....

To determine the information size of the article in kilobytes (KB), we can break the problem down step by step.

### Given Information:
- The article has 20 pages.
- Each page has 40 lines.
- Each line has 48 characters.
- Each character is encoded as 2 bytes in the Unicode representation.

### Steps to Calculate:

1. **Total number of characters:**
   \[
   \text{Total characters} = (\text{Number of pages}) \times (\text{Lines per page}) \times (\text{Characters per line})
   \]
   \[
   \text{Total characters} = 20 \times 40 \times 48 = 38,400 \text{ characters}
   \]

2. **Total size in bytes:**
   Since each character is encoded as 2 bytes:
   \[
   \text{Total size in bytes} = (\text{Total characters}) \times (\text{Bytes per character})
   \]
   \[
   \text{Total size in bytes} = 38,400 \times 2 = 76,800 \text{ bytes}
   \]

3. **Convert bytes to kilobytes:**
   1 kilobyte = 1024 bytes. Therefore:
   \[
   \text{Total size in kilobytes} = \frac{\text{Total size in bytes}}{1024}
   \]
   \[
   \text{Total size in kilobytes} = \frac{76,800}{1024} = 75 \text{ KB}
   \]

### Final Answer:
The information size of the article is **75 kilobytes (KB)**.

Here are 5 related questions for further practice:
1. If each character were encoded using 1 byte instead of 2, what would be the new file size in KB?
2. How would the file size change if the number of lines per page were doubled but the number of pages halved?
3. How many bits does the article take up in total, given the 2-byte character encoding?
4. If the encoding scheme changes to 4 bytes per character, what would be the new file size in KB?
5. How much space would the article take up if it were saved as plain ASCII, with 1 byte per character?

**Tip:** Always double-check unit conversions, especially between bytes and kilobytes, as they often use a base of 1024 instead of 1000.

The article, typed on a computer, contains 20 pages, each page has 40 lines, and each line has 48 characters. In one representation of Unicode, each character is encoded as two bytes. Determine the information size of the article in kilobytes in this Unicode representation variant.
