It is a classic Ordinary Annuity saving plan. The general formula is 


    FV = ,    (1)


where  FV is the future value of the account;  P is your monthly payment (deposit); r is the monthly percentage yield presented as a decimal; 
n is the number of deposits (10, in this case).


Under the given conditions, P = 6000;  r = 0.12/12;  n = 10.  So, according to the formula (1), you get at the end of the 10-th month


    FV =  =  = $62773.28.


Note that Cardo deposits only  10*$6000 = $60,000.  The rest is what the account earns/accumulates in 10 months.
