CREATE TABLE table_name_53 (engine_capacity NUMBER, mpg_us_urban VARCHAR2, mpg_uk_urban__cold_ VARCHAR2, mpg_uk_extra_urban VARCHAR2)

What's the engine capacity when the mpg-UK urban is less than 12.2, the mpg-UK extra urban is less than 18.8 and the mpg-US turban is less than 7.2?
SELECT SUM(engine_capacity) FROM table_name_53 WHERE mpg_uk_urban__cold_ < 12.2 AND mpg_uk_extra_urban < 18.8 AND mpg_us_urban < 7.2
SELECT SUM("engine_capacity") FROM "table_name_53" WHERE "mpg_uk_extra_urban" < 18.8 AND "mpg_uk_urban__cold_" < 12.2 AND "mpg_us_urban" < 7.2
