Inches or centimeters
i would use decimeters for a reading book. for textbooks, i would use inches
Kilograms
I think I saw that you tried to include that your units were in inches. this is not a metric unit to start. convert inches to centimetres. then multiply the length by the width to get your answer in cm^2, a metric unit
Most like a vernier caliper for accurate readings
Try using a triple beam balance, or a electronic scale. The units to measure the mass of the book would be in grams.

0 - 1 inch Micrometer might be better to measure 10 pages and find the average.
Centimetres.
I would measure it with a ruler.

To find the area of a book cover in metric units, the most appropriate unit to use would be centimeters. The formula for finding the area of a book cover would be: length x width.
You would typically use inches to measure a paperback book. You can measure the length, width, and thickness of the book in inches to determine its size.

Inches or centimetres are fine for a book's dimensions. Measure the width, height and depth to determine the volume. If you are talking about the length of the book's narrative, word count is probably the most accurate.

Probably centimeters.
Any sort of scale can be used to measure weight, which can then be used to help calculate mass. There do exist 'massometers', but those are usually less common except in laboratory environments.
