Do you know whice is the tallezt buildin in the wolrd? It's the Burl Khalifa!
Corrected text: "Do you know which is the tallest building in the world? It's the Burj Khalifa!" 

The misspelled words are "whice" (correct spelling: "which"), "tallezt" (correct spelling: "tallest"), "buildin" (correct spelling: "building"), and "wolrd" (correct spelling: "world"). The correct spelling of the building's name is "Burj Khalifa," not "Burl Khalifa."
