One cubic foot of air can float approximately 0.0807 pounds (or about 36.5 grams) of weight due to its buoyancy in a denser medium, like water. This is based on the average density of air at sea level, which is about 0.0807 pounds per cubic foot. In practical terms, this means that if you have a balloon filled with air that displaces one cubic foot, it can lift that amount of weight.
How much does it cost to install a central air conditioner per sq foot
There is really not much you can do about it.
you will probably will require 10 AC 5000 sq feet room
Yes, apples contain about 25 percent air, which contributes to their buoyancy and allows them to float in water. The air pockets within the apple's structure make it less dense than water, enabling it to stay on the surface. This characteristic is part of what gives apples their unique texture and helps them remain buoyant.
this is a pretty good party trick. tip your head back and pucker your lips, then blow out to make a strong stream of air straight up. then place the ping pong ball in the air stream and it will float! tip: keep the air stream strong and constant and you should be able to keep it up for 4-5 seconds before gravity takes over.
you need a 100 foot tall crane with thin wires in broad daylight
None at all.
None, since there can be no conversion.A cubit equals 1.5 feet so a cubit foot equals 1.5 square feet which is a measure of area in 2-dimensional space. The amount of air breathed requires a measure of volume in 3-dimensional space. The two measures are different and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
No a train does not float in the air, no train does.
Objects filled with air float on water because the density of air is much lower than the density of water. This creates buoyant force, which causes the object to float. The air-filled object displaces an amount of water equal to its weight, allowing it to stay afloat.
Everything I can find says that a cubic foot of air can lift about 62-63 lbs.

The float has air in it.
1 cubic foot of air will support 62 lbs
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Because it has air in it. Air weighs less than water therefore air floats.
To determine the volume of air needed to float an object, you need to know the density of air and the weight of the object. For example, if the density of air is approximately 0.075 lb/ft³, then to float a 1000-pound object, you would need approximately 13,333.33 ft³ of air (1000 lb / 0.075 lb/ft³ = 13,333.33 ft³).
