Answer:
The answer is 18.2045
Step-by-step explanation:
In order to determine the rounded number, we have to know about the notation numbers. In any number, every digit has a unique notation depending on his place.
I have attached an image that shows some notation numbers. We can see that the hundred-thousandth place is the fifth digit after the decimal point.
Then we have to see the next digit. If the digit is greater or equal than 5, we have to increase in one unit the number in the place we want to round. If not, the number does not change.
In this case:
Fifth decimal number is 9
Sixth decimal number is 8, so we have to increase 9 by 1.
Finally the number is 18.2045

Important Information:
A Book Has 12 Chapters.
The Mean length of the chapters is 40 pages.
Question to Answer:
How many total pages are there in the 12 chapters?
Explanation/Solution:
Let's assume that the total number of pages in the book is "x" pages.
To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.
=40
Multiply both sides by 12...
x = 480
Hence, The total number of pages in the 12 chapters is 480.
