The calculation formula of land mu is 1 mu =60 abbots = 6000 square feet, 1 mu =666.667 square meters. We usually do not use this value to calculate the number of mu, but use a simpler calculation method.
The formula is: length (m) × width (m) ×0.00 15= mu. For example, the land area with a length of 200m and a width of 150m is 200 (m )×150 (m )× 0.0015 = 30,000 square meters× 0.0015 = 45 (mu).
Usually, a relatively simple calculation method is used to check the number of acres. The formula is: length (m) × width (m) ×0.00 15= mu number. For example, the land area of 200m long and 150m wide is 200 (m) ×150 (m) × 0.0015.
Mu is the unit of land area in China, which is equal to 60 square meters, or about 666.67 square meters. Fifteen acres equals one hectare. The 60-square abbot was chosen because of the ancient counting method in China. At present, most counts are based on ten, while in ancient times, most counts were based on 60. For example, a nail is 60 years.
The importance of learn mathematics:
1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.
2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.
3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
