@Olha Oleshko Your question translated by Google Translate is:

Good day Do I understand correctly that a school with 10 teachers, each of whom has 10 students, can use the education plan for free?

Qualifying for the Miro Education Plan is not determined by the number of teacher or students. Instead,  an application being approved depends on whether you are a student or a teacher/education of a qualifying education institution.

More information can be found in the Education Plan help center article, along  with the application form link (search the page for "application form"):

Note: If you are unable to complete the application form due to your educational institution not providing you with an email address, please leave a reply in this post:
