A ping pong ball is hollow and filled with air. A golf ball is solid inside. If you hold one in each hand you will feel the difference in weight.
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.
you put a hole in it
Yes it does.
The number of ping pong balls needed to get a steel cube to float would depend on the mass of the steel cube.
It is lighter than water and is hollow with air.
without goin too nerd on you, It is coz of the air inside the ping pong and the plastic is very light. making it "weightless" and it can float because it is less dense than water
