Measuring the volume of an oddly-shaped object is difficult, but in this case there's a relatively good shortcut: the density of a human being is approximately that of water. So, if you take the mass of the five-year-old in question:
mass / density = mass / (mass/volume) = volume
I don't know about the mass, but the density of water is almost exactly one gram per cubic centimeter.

water weighs about 64 pounds per cubic foot
most 5 year old boys float which makes them just a bit less mass that water of the same volume
weigh your 5-yr-old and then divide by about 60, that should be approx number of cubic ft

Weigh him. His specific gravity will be about the same as that of water. One cubic foot of water weighs 62.4 lbs, so see how many times 62.4 divides into his weight in lbs and you have his volume in cubic feet.
Example:
If he weighs 84 lbs.
84/62.4 = 1.35 cu ft.

such a great question..only smart people can get it....
10^1000000 cubic feet...lol
good luck:)

age is not an indicator of volume

Multiply his length, width, and height to get an approximate answer.
