Table schema:
CREATE TABLE table_name_33 (weight VARCHAR, internal_storage VARCHAR, wireless_network VARCHAR)

Question: What is the weight of the display that has an internal storage of 16-64 GB and uses a wi-fi, 3G wireless network?
SQL: SELECT weight FROM table_name_33 WHERE internal_storage = "16-64 gb" AND wireless_network = "wi-fi, 3g"
