Michael estimated his mass as 8 kilograms. Is his estimate reasonable? Justify your answer. Please help me thanks.
2.2 pounds = 1 kg
8 kilograms = 17.6 pounds
Michael is right -- if he's a 6-month-old baby.

not unless he is a baby
That is around 18 pounds in American units, too young to estimate his own mass.
