Advanced Grammar in Use Unit 89 Page 178

If you put a countable noun between the adjective and the second as, you should use a/an in
front of the noun (if the noun is singular):
• Despite his disability, he tried to lead as normal a life as possible.
• She was as patient a teacher as anyone could have had.
The negative form of sentences like this can use either not as or sometimes not such:
• He's not as good a player as he used to be.
• He's not such a good player as he used to be. (Notice the different word order.)
• They're not such terrible children as we'd expected. (We don't use not as with plural nouns.)

We can use how, so and too followed by an adjective in a similar way:
• How significant a role did he play in your life?
• It's not quite so straightforward a problem as it might at first seem.
• 'Conspiracy' is perhaps too strong a word.
• How big a piece do you want?

Thanks Mr Essam, you are wonderful
