A solution containing active cobalt `60/27` Co having activity of `0.8 muCi` and decay constant `lambda` is injected in an animal's body. If `1cm^(3)` of blood is drawn from the animal's body after 10hrs of injection , the activity found was 300 decays per minute. What is the volume of blood that is flowing in the body ? (`1 Ci = 3.7 xx 10^(10)` decays per second and at `t = 10` hrs `e^(-lambdat) = 0.84`)
