Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Question ###
What is Average Height, when Weight is less than 93, when Spike is less than 336, and when Block is 305?

SELECT AVG(height) FROM table_name_82 WHERE weight < 93 AND spike < 336 AND block = 305
