You can measure:
1 and 0- 1 Yes 1.
2,0-6 is 6.
3, 0-8 is 8.
4. 1-6 is 5.
5. 1-8 is 7.
Six, six, eight equals two.
There are six kinds without overlap, and there are more overlapping measurements.
Extended data
When recording the measurement results, the corresponding units must be filled in. The key to correct placement is: the edge of the ruler is aligned with the measured object, which must be aligned and overlapped, and cannot be skewed; The facet of the ruler must be close to the measured object and cannot be "suspended".
First, check whether the zero scale of the scale is worn. If it is worn, re-select a scale value as the starting point of measurement. Secondly, look at the measuring range (range) of the scale. In principle, the length measurement needs a measurement. If the measuring range is smaller than the actual length, the ruler needs to be moved many times, which will lead to a large error.
The length value represented by the minimum scale not only reflects the different precision of the scale, but also relates to the validity of the measurement results. The measurement range and minimum calibration value should be selected according to the actual measurement requirements. The minimum scale of the triangular ruler used by students is mm, which is used to measure the length of 2cm. If the scale line is just aligned, the correct record should be 2.00 cm, where 2.0 cm is the number accurately read on the surface of the scale.
