The metric unit commonly used to measure the area of a book cover is square centimeters (cm²). This unit is derived from the metric system's base unit of length, the centimeter, and is used to quantify the two-dimensional space occupied by the book cover. To calculate the area of a book cover, you would multiply the length and width of the cover in centimeters to obtain the measurement in square centimeters.

Inches or centimeters
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.
A phone book has 3 dimensions, and they are length, width, and thickness. It has 6 faces, and they are the front, back and the four "sides" or "edges" of the book. These are all faces, and the surface area will have to account for all the faces. Let's break it down and find that surface area. Picture the book on a table in front of you with the back of the book (called the spine) on your left. The book's cover is length x width, and you have a front and back cover. Take that length x width x 2 to find the area (in square units) of the front and back covers. Now all you have to do is take the thickness x length x 2 to find the area of the back of the book and the front of the book, and then take the thickness x width x 2 to find the area of the bottom and top edges of the book. Add the three numbers and you have the surface area of the book. Want an example? Let's have at it. A 4 inch thick phone book has covers that are 8 by 11 inches. The covers (both of them) are 8 x 11 x 2 = 176 in2 for an area. The front and back sides or edges of the book have an area that is 4 x 12 x 2 = 96 in2 for an area. The top and bottom sides or edges are 4 x 8 x 2 = 64 in2 for an area. We have 176 + 96 + 64 = 336 in2 for the surface area of that phone book. Simple once you break it down and think it through.
Try using a triple beam balance, or a electronic scale. The units to measure the mass of the book would be in grams.
centimeter
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.
meters2
If it's a standard book, the standard units would probably be cm2.
Square centimetres and square metres are measures of area in 2-dimensional space: they cannot be used to measure the length of a book cover which is a 1-dimensional measure.
(length of the cover) times (width of the cover) is.
The area of a book cover would depend on the dimensions of the cover. To find the area, you would multiply the length by the width of the book cover. Formula for area of a rectangle is length x width.

The 'area' of a telephone book - is simply the geographical coverage. Some books only cover a single town - others cover whole counties.
