Question

В книге 250 страниц. На одной странице 55 строк. В каждой строке 40 символов. Какой объём занимает данная книга? И сколько таких книг поместится на USB накопителе объемом 2гб?

Answer 1

1) 250 * 55 * 40 = 550000 всего символов в книге
2) В стандартной кодировке 1 символ кодируется 1 байтом, значит
550000 * 1 = 550000 байт =  537,1 Кб объем информации в книге
3) 2ГБ = 2048 МБ = 2097152 КБ
4) 2097152 / 537,1 = 3904 книги поместится на флешке

Answer 2

Calculating Book Size and USB Storage Capacity

To calculate the volume of the book, we can use the following formula:

Number of pages × Number of lines per page × Number of characters per line

Given: - Number of pages = 250 - Number of lines per page = 55 - Number of characters per line = 40

Using the formula: 250 pages × 55 lines per page × 40 characters per line = 550,000 characters

Now, to determine how many such books can fit on a 2GB USB drive, we need to consider the size of the book in terms of bytes and then compare it to the storage capacity of the USB drive.

Book Size in Bytes

To calculate the size of the book in bytes, we need to consider the character encoding. Assuming each character is encoded in 1 byte (which is the case for many common character encodings), the size of the book in bytes would be the same as the number of characters.

So, the size of the book in bytes is also 550,000 bytes.

USB Storage Capacity

A 2GB USB drive can hold 2,147,483,648 bytes (2GB = 2,147,483,648 bytes).

Number of Books on USB Drive

To find out how many such books can fit on the USB drive, we can use the following calculation:

Number of books = USB storage capacity / Book size

Substituting the values: Number of books = 2,147,483,648 bytes / 550,000 bytes ≈ 3.9 books

Therefore, approximately 3 books of this size can fit on a 2GB USB drive.
