How big is the book of A5?,The size of the book of A5.

The length, width and area of the book A5 and B5 are different.,B5 is larger than A5.。

According to the basic area of the paper format, the format specifications are divided into A series, B series and C series, the format size of A0 is 841mm 1189mm, and the format area is 1 square meter; The format size of B0 is 1000mm 1414mm, and the format area is 2 5 square meters; The size of C0 is 917mm 1279mm, and the area is 2 25 square meters.

If the A0 paper is split into two equal parts along the length, it becomes the A1 format, and if the A1 paper is split along the length, it becomes the A2 format, and so on to the A8 format; B8 paper is also folked to B8 size according to this method. The format sizes of A0 A8 and B0 B8 are shown in the table below. Among them, 7 format specifications, such as A3, A4, A5, A6 and B4, B5 and B6, are commonly used for copy paper.

A5 paper size: 148mm x 210mm; A5 paper is the size of a paper that folds a size paper in half 5 times, and the A5 book is equivalent to a 32K notepad.

In 1965, the national standard stipulates that the opening of books and magazines should be divided into three groups: A, B, and C, and Group A is cut from the original whole sheet of paper of 880 mm and 1230 mm, Group B of the original paper is 787 mm and 1092 mm, and Group C of the original paper is 695 mm and 960 mm. In 1982, GB788-87 emphasized the adoption of international standards. The new standard retains the A series that conforms to the international standard in the old standard, and at the same time adopts the international standard B series, and eliminates the B and C groups in the original standard.

Its purpose is to promote foreign and international exchanges. What we call A4 and B5 when we make copies is an international standard.

a3＝297×420mm

a4＝210×297mm

a5＝148×210mm

b4＝257×364mm

b5＝182×257mm

Above are different notebook sizes and hopefully ......

The length, width and area of the book A5 and B5 are different, and the relative area of B5 is larger.

1. The area of the A specification in the international size is larger than that of the B specification, and the following number represents the number of folding times of the basic specification size, such as B5 is the size of the basic specification of the B type folded five times.

2. The format size of A0 is 841mm 1189mm, and the format area is 1 square meter; The format size of B0 is 1000mm 1414mm, and the format area is 2 square meters.

3. The standard stipulates that the ratio of the width (represented by x) and the length (expressed by y) of the paper is x:y=1:n.

B5 is bigger than A5's book.。 The paper size of A5 is: 210 mm 148 mm; The paper size of B5 is:176 mm 250 mm,So after calculation and comparison,B5 is larger than A5's book.。

In addition, the paper size refers to the size range of the folding machine that the folding machine can support the line of paper, generally including a maximum size and a minimum size, which is generally expressed by the size of the paper. If the paper is larger or smaller than this size range, the product will not be able to fold and collate it.

A6's comparatively larger.

A5: 210 mm 148 mm. The size of the A6 is 105 mm wide and 148 mm. B5 paper size is: 176*250mm.

Generally, copy shops can copy documents of A4, A3, B5 and other sizes.

According to the size, there are usually three types, large folio, medium folio, and small folio.

Note: B5 copy paper should be stacked when taking the paper, and the lower part of the upper stack and the upper part of the lower stack should not be put into the same paper supply box together. Before loading and placing B5 copy paper, the paper needs to be fully twisted to reduce the adhesion between the paper.

Algebra is arguably the most widely accepted form of "mathematics". It can be said that since everyone started learning to count when they were young, the first mathematics they came into contact with was algebra. As a discipline that studies "numbers", algebra is also one of the most important components of mathematics.

Geometry. It was the first branch of mathematics that began to be studied.

Until the Renaissance of the 16th century.

Descartes founded analytic geometry, linking algebra and geometry, which were completely separate at the time. Since then, we can finally prove the theorems of geometry with calculations; At the same time, it can also be used to visualize abstract algebraic equations and trigonometric functions.

Later, calculus was developed into more subtle forms.

A5 book is big.

A5 paper size: 148mm x 210mm; A5 paper is the size of a paper that folds a size paper in half 5 times, and the A5 book is equivalent to a 32K notepad.

In 1965, the national standard stipulates that the opening of books and magazines should be divided into three groups: A, B, and C, and Group A is cut from the original whole sheet of paper of 880 mm and 1230 mm, Group B of the original paper is 787 mm and 1092 mm, and Group C of the original paper is 695 mm and 960 mm.

In 1982, GB788-87 emphasized the adoption of international standards. The new standard retains the A series that conforms to the international standard in the old standard, and at the same time adopts the international standard B series, and eliminates the B and C groups in the original standard. Its purpose is to promote foreign and international exchanges.

What we call A4 and B5 when we make copies is an international standard.

B5 has a larger relative area. Size of A5: 148 210, size of B5:

176 250 The area of the A specification is larger than that of the B specification, and the following number represents the number of folds of the basic specification size, such as B5 is the size of the basic specification of the B type five times. Among them, the format size of A0 is 841mm 1189mm, and the format area is 1 square meter; The format size of B0 is 1000mm 1414mm, and the format area is 2 square meters.

Set A paper. The basis for the development of the A series was to first find a sheet of paper with an aspect ratio of 2 and an area of 1 square meter (m). Therefore, the width and length of this sheet are 841 mm and 1189 mm respectively (the aspect ratio is 2:

1), and it is numbered A0. If the long side of the A0 paper is cut in half, two sheets of A1 paper are obtained, both with a width of 594 mm and a length of 841 mm.

If you continue to cut the A1 paper in half in this way, you can get the paper sizes of A2, A3, A4 and so on in order. Dimensions are rounded to the whole number when setting standards, so paper sizes with decimals (less than 1 mm) are rounded.

Refer to the above; Encyclopedia - A4 paper.

B5's book is big. The paper size of B5 is: 176 mm to 250 mm, while the paper size of A5 is:

210 mm 148 mm. So B5 is bigger than A5's book.。 A5 paper is to fold the basic size of A-type paper 5 times, so the area of a piece of A5 paper is 1/5th of the area of 2 of the basic paper, that is, 1 32.

B5 paper refers to B5 size paper. B5 generally has two sizes, extra, that is, the international standard size, that is, 176mmx250mm is universal. The specification of paper refers to the fact that after the paper is made, it is trimmed and cut to a certain size.

The size of the A5 paper is half of the size of the A4 paper, and you can get two A5 sheets by folding the A4 paper in half.
