For regular compound interest the formula is:
A = P(1 + r/n)nt
A = future or final amount
P = principal investment = $600
r = interest rate as a decimal = .03
n = number of times interest is compounded per year = 365
t = time in years = 3
A = 600(1 + .03/365)365(3)
A = $656.50
Hope this helps. Good luck.
