Calculator, tape measure and carpentry 1. Use a special tape measure. Usually the ruler is 10 cm, the actual length is only 9 cm, less 10%. If you purchase 3,000 yuan wood at one time, you would earn 300 yuan more. Carpenters generally know, but they will not speak. Usually the wooden side is bought to be sawn into a wooden strip to do the ceiling or the partition wall, so we generally recommend the customer directly to buy the finished white pine, calculate the price according to the root, so it is not easy to JS flicker to.
2, the calculation of the volume Even if you and woodwork together to buy wood, but it will not necessarily follow the calculation of wood volume. At this time, JS often directly multiplies the length of the wood by the width and reports the area by volume to the user. The result may be double the price to buy wood. For example, wood that is 4 meters long, 0.25 meters wide, and 0.05 meters thick should be calculated as 4*0.25*0.05=0.05 cubic meters, but as long as you neglect, they will be regarded as 4*0.25=0.1 cubic meters, a difference of two times. There are many tricks for such calculation methods.
3. If the purchaser himself does not have a calculator, even if he has a calculator, he will not suspect that the calculator has a remote control. The remote control is usually placed in the pocket. When the calculator is in operation, press the remote control for 10%, and press the remote control for 20%. If you use the calculator they prepared in advance, as long as the other party presses the same number of times, how to calculate the result will be the same.
