Pretty sure, just from memory... it is "What is in your backpack and How many doors are in your house" odd sentence.
¿Qué hay en tu mochila?
Que -> what en > inside tu > you or your casa>house hay> there is/are Que hay en tu casa means, "what is there in your house?"
"Que hay en tu escuela" in English means "What is in your school?"
"Que hay en tu dormitorio" translates to "What is in your bedroom?" in English. The phrase is asking about the items or things present in someone's bedroom.
what is in your room
It means, "What is there inside your backpack?" It could also mean, "What'cha got in the backpack?"
It means "in your backpack".
Do you have a ruler in your backpack??? Um...yo no se...tu tienes??? por que esta pregunta??? it doesn't make sense...
What is your school like? e.g Mi instituto es guay!
who is in your clase What is there in your class? This doesn't make a whole lot of sense. You might want to say "Quién está en tu clase?" meaning "who is in your class?"
