    Dear Jonathan,
    
    You have it just backwards...   
    A 1cm cube has an frontal area of 1 square cm and a mass of 1 unit,  
    
    A 10cm cube has an area of 100 square cm,  but a MASS of 1000 units,
    
    So it will have more momentum to overcome friction with the atmosphere,
    hence will decay much more slowly...
    
    Hope this is helpful.
