Answer is: 2,469 mL give to the child.

The mass m in kilograms (kg) is equal to the mass m in pounds (lb) times 0,45359237: m (child) = 72,6 · 0,045359237 = 32,93 kg.

m (Medrol) = 32,93 kg · 1,5 mg/kg.

m (Medrol) = 49,39 mg.

d (Medrol) = 20,0 mg/mL.

V (Medrol) = m (Medrol) : d (Medrol).

V (Medrol) = 49,39 mg : 20 mg/mL.

V (Medrol) = 2,469 mL.
