I would measure it with a ruler.
To use inches to measure a math book would make more sense, but feet does too, since a math book's length on the binding side is close to a foot. Inches makes the most sense though.

inch or centimeter
Neither. A kilogram is a measure of mass, not weight. A maths book is more likely to have amass of 2 kg.

It would have to be a very thin book if it was.
Measure what? Their mass, length, volume?
