The metric unit commonly used to measure the length of a book would be centimeters (cm) or millimeters (mm), depending on the size of the book. For larger measurements, meters (m) could also be used. These units provide a more precise and standardized way of measuring length compared to imperial units like inches or feet.
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
You would typically use centimeters (cm) or millimeters (mm) to measure the width of a book. These units provide a more precise measurement for smaller objects like books.
Try using a triple beam balance, or a electronic scale. The units to measure the mass of the book would be in grams.

You would use a ruler or a meterstick to measure the length of the strap on your book bag. A yardstick is typically used for larger measurements and may not be as precise for measuring smaller objects like a strap.

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.
one page of a phonebook is measured in mm. unit thickness of a phone book is cm
