sorry. dont have the textbook
Mathway is a very good website where you can get solutions for math questions.
I do not have your textbook. Either you have one or you know someone (e.g. classmate) who has one. Therefore you are more likely to encounter the textbook than I am, so I will leave it to you to find the questions..... sorry.
we dont know what the name of this online math textbook is. you must be more specific.
Math makes sense but apparently your question does not. Please do not post questions that require us to have your textbook, because 99% of us won't.

Well, I would recommend finding math textbooks from the company of the manufacturer of the textbook's website. There is a most likely chance that math textbooks can be found on their website.
The volume of a math textbook would depend on its physical dimensions. It can be calculated by multiplying the length, width, and height of the textbook. A common unit for volume is cubic inches or cubic centimeters.
Lots of practice is one answer. When Pascal was asked 'how to become an expert mathematician', his answer was 'find an insoluble problem and attempt a solution.' Another solution would be to attempt to answer for yourself, some of the math questions in wikianswers.
If your teacher gave you a password to get into the book you can find it online. I do not have access to that book. Try it and see if you have access to it. Maybe a classmate knows the passwords to get online.
