(in Cubic Feet)

Since a human body is about the same density as water (and is mostly made of water already), one can assume that the weight of water would apply almost directly.
1 cubic foot of water weight 62.428 pounds.
Divide the weight of the boy (a 5 year old probably weights 45 lb on average) by 62 to get a rough but still pretty good estimate of the volume in cubic feet.

Put into a bathtub sufficient and determined quantity of water in cubic feet where the 5-year old boy could be completely submerged and will not overflow the bathtub.
Submerged completely the boy and determine the volume of water while he is still completely submerged.
Deduct the volume of water you put into the bathtub from the volume while the boy was completely submerged.
Answer: The difference between the volume in cubic feet while the boy is completely submerged less the volume in cubic feet you put into the bathtub is the volume of the 5-year old boy you submerged into the bathtub.

In the lab this would be done by having a measured amount of water(enough to cover him) Placing him under water and seeing how much the water level rose. The rise is the volume of the boy. Since boys vary, this needs to be done.
