Can you reasonably install auditorium chairs by calculating the number of rows?

The standard width of each row of front and rear seats (auditorium chairs) is 100 cm, but the minimum should not be less than 90 cm (auditorium chairs with writing boards should consider whether the writing board in the rear row can be put down), the total length of the venue minus the reserved aisle. Divide the width by 90 or 100 cm, rounded up as a whole number, which is the total number of rows. The multiplication is the total number of chairs in the entire field. It is important to note that if the site is a ladder, it is recommended to build a 90~100 cm step. If it is a slope and the architectural design cannot be found, you can use a multi-function slope measuring instrument (online), select several points for measurement, take the average value, if the diameter of the arc is greater than 17 meters, then produce and install according to the normal size, if it is less than 17 meters m, the specific situation should be dealt with on a case-by-case basis.
