Step-by-step explanation:
The United States spent $26 billion in war recovery aid through the Marshall Plan between 1946 and 1949. However, the question specifically asks about the years 1948 to 1952. Unfortunately, I couldn't find any specific information regarding the overall spending in cash and commodities during those years. I would recommend referring to historical records or textbooks for more specific information about the expenditure during that time period.
