Question

how to say "how much does this white shirt cost" in Spanish ?
how much would be cunato, this would be esta, white shirt would be camisa blanco, cost would be cuesta

how can i connect them all together in one sentence ?

Answer

The structure is as follows:

Question word + action (verb) +  direct object =   
¿Cuánto cuesta esta camisa blanca? ¿Cuánto vale esta camisa blanca? 
Informal: ¿Qué cuesta esta camisa blanca? ¿Qué vale esta camisa blanca?

But you ask about the price in a different way:
question word + price+  action (verb) + direct object : ¿Qué precio tiene esta camisa blanca?

Espero haberte ayudado :)

Answer

¿Cuánto cuesta esta camisa blanca? o ¿Cuánto vale esta camisa blanca?
