The golden ratio is approximately 1.618.
The A4 paper uses something known as the Lichtenberg ratio 1:sqrt(2). If you cut a piece of A4 paper in half, the sides of the smaller sheets would maintain the same ratio. That's why A4 is exactly half the size of an A3 sheet, and A3 is exactly half of an A2 sheet, and so on.

Examples of Golden rectangles?
Any sheet of paper in the An series - A4 being the most common size for printers and copiers.
How do you factor fully 'a4 plus 4b4?
(a2+2b2-2ab)(a2+2b2+2ab)
What is a squared x a squared?
If you mean a2 x a2... the answer is a4
If a b c 0The value of a4 b4 c4b2c2 c2a2 a2b2 is?
Expand 4ab3 (a2b2-a-1)
How do you factor of a4 plus b4-7a2b2?
Usually simple substitutions enable such expressions to be seen as quadratic expressions. The substitutions x = a2 and y = b2 give a4 + b4 - 7a2b2 = x2 - 7xy + y2 which does not have any rational factors. Consequently, the quartic in a and b does not have rational factors.
How do you photocopy a of a4 paper to a a3 of paper?
A4 paper is exactly half the size of A3, and they both have the same aspect ratio. So A4 --> A3 is an enlargement. Most photocopiers use A4 as standard. You need a larger photocopier to copy onto A3. The photocopier will usually offer A4 --> A3 as an option.
Is an A4 sheet of paper a golden rectangle?
No. The ratio (length : width) of the sides of a sheet of the A series of papers (of which A4 is one) is √2 : 1 ≈ 1.414 : 1 Alternatively, the ratio can be expressed as 1 : 1/√2 ≈ 1 : 0.707 A golden rectangle has sides in the ratio (length : width) of φ : 1 = (√5 + 1)/2 : 1 ≈ 1.618 : 1 Alternatively, the ratio can be expressed as 1 : 1/φ = 1 : 2/(√5 + 1) = 1 : (√5 - 1)/2 ≈ 1 : 0.618
What are some objects that have a golden rectangle?
flowers, building, an A4 paper etc. mostly in nature.
What would be an example of A3 paper?
a paper smaller than the average sized printer paper (A4)
What is A4 paper?
A4 is the standard size of paper used for computer printouts and other uses.A4 paper is 210 × 297 mm. It has an area of 1/16 square metres.It is one of a series of paper sizes starting with A0, which has an area of 1 square metre.Another AnswerThe advantage of using A-series of paper sizes is that the height to width ratio remains constant throughout the series. So, if you were to fold an A4 sheet in half, you would have an A5 sheet of identical ratio. Reducing an A4 document to A5 will result in the same proportion of white space around any text area as there was on the original A4 document. This is not the case, for example, with US letter size -if you fold this in half, the ratio of height to width changes significantly making it impossible to reduce any text area in proportion when copying.
What are some examples of the golden rectangle?
Sheets of paper in the A and B series (A4 being the most common).
Why do people use the golden ratio?
There are several reasons. Two of them are:1. It is said to be aesthetically pleasing.2. It allows standard sizes of paper, such as A0, A1, A2, A3, A4, A5 etc and the B0, B1, etc where each size shares the measure for one side with its neighbour, and its other side is half that of its left neighbour and double that of the one to its right. The ratio of the two sides of any one of these sheets of paper is the Golden Ratio.
Examples of Golden rectangles?
Any sheet of paper in the An series - A4 being the most common size for printers and copiers.
What is the size of A4 paper in inches?
A4 paper size is 8.3in × 11.7in.
How do you use the golden rectangle in everyday life?
If you use A4 paper (rather than letter size) you are using it. every day.
Why is the golden ratio used?
There are two main areas where the ratio is used and they are for different reasons.One reason is that the human mind finds the Golden ratio aesthetically pleasing. It is, therefore, used in art and architecture.The second reason is directly related to its mathematical properties (the ratio of the whole to the larger part is the same as the ratio of the larger to the smaller parts). This is used in designing paper sizes like the A and B series. Divide an A3 sheet in half and you will get two A4 sheets which have the same aspect ratio as the A3. Repeat and you get two A5s with the same property and so on.
How many A4 paper go into A1?
8 A4 peices of paper and a third
