What does por que te usta la clase en numero 6 mean?

The sentence "por que te usta la clase en numero 6" is grammatically incorrect in Spanish. Here's why:

* "Usta" is not a correct verb form. The correct form is "gusta."

* "En numero 6" is redundant. "Numero" is already implied in "6."

Here are some possible corrections, depending on what you want to say:

Option 1: Asking why someone likes class number 6

* ¿Por qué te gusta la clase número 6? (Why do you like class number 6?)

Option 2: Asking why someone likes the class that is in room 6

* ¿Por qué te gusta la clase que está en la sala 6? (Why do you like the class that is in room 6?)

Option 3: Asking why someone likes the sixth class

* ¿Por qué te gusta la clase número 6? (Why do you like the sixth class?)

Option 4: Asking why someone likes the class that is sixth in a sequence.

* ¿Por qué te gusta la sexta clase? (Why do you like the sixth class?)
