1, textbook size:

There is no uniform standard for the size of textbooks, and different textbook publishers and versions may be different. Generally speaking, the size of primary and secondary school textbooks is A4 or B5, that is, 2 10mm×297mm or 176 mm× 250 mm ... According to this size, the approximate area of textbook cover can be estimated.

2. The influence of cover design on this area:

The cover design of mathematics textbooks usually includes such elements as title, pattern and illustration, which will affect the cover area. Some textbooks may only place titles and patterns in a certain area of the cover, leaving other areas blank. So the cover area of different textbooks may be different.

3, the role of textbook cover:

The cover of the textbook is the image representative of the textbook. Excellent textbook cover design can combine visual beauty and cultural connotation to convey the main ideas and contents of textbooks. The cover design of textbooks often determines the readers' acceptance. In China, the cover design of textbooks is usually called the overall design or artistic design of books.

Definition and calculation method of area:

1, the definition of area:

Area is a quantity indicating the degree of a two-dimensional figure or shape or plane layer in a plane. Area can be understood as the amount of material with a given thickness required to form a shape model, or the amount of coating required to cover a surface with a single coating. It is a two-dimensional simulation of curve length or solid volume (three-dimensional concept).

2, the calculation method of area:

(1) The calculation method of regular object area is: length times width, edge times edge, and bottom times height. The area formula of a rectangle is length times width, s = a× b; The area formula of a square is edge times edge, s = a× a; The area formula of parallelogram is base times height, and s = a× h.

(2) Irregular objects: By addition calculation, the irregular objects are divided into two regular objects, and then their areas are calculated separately, and then the final area can be calculated by adding the areas together. You can also use the method of recombination to combine some irregular objects into a regular object and then calculate the area. This is the reorganization method.
