No, that would not be reasonable to say.
If you were filling some buckets, you could say 4 gallons, but we’re talking about a bowl and at the most that will take just a few cups.
I hope this helps and please let me know if you need further explanation!

Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
