英语在多少页怎么说

To ask how many pages something is in English, you can say "How many pages is it?" or "What is the page count?" For example, you could say:

"I'm looking for a book to read. Do you know how many pages it is?"

"I have a report to write, but I'm not sure how long it should be. What is the page count for this assignment?"

You can also use the word "length" to refer to the number of pages:

"I'm trying to decide which book to buy, but I'm not sure which one is longer. Do you know the length of each book?"

"I want to make sure I have enough time to read this book. Can you tell me the length of the book?"

I hope this helps! Let me know if you have any other questions.
