how would you find the density of something round and hollow that you can't open?

I think you would fill a beaker to the very top with water and then have a container below it. Put the object in the water and then push the object down so water would spill over. The measure the amount of water that flowed over. Then, weigh the object. The solve the equation mass over volume. Because the is density.

It is a good question wouldn't you have to fill a beaker with water and mass it and then put the hollow object in and see how much the rose?

I want to add. Won't you have to measure the beaker first and then fill the beaker and then subtract the math.

how would you find the density of something round and hollow that you can't open? you can still find the mass of an object by putting it on a scale, and find the volume by filling a beaker full of water, putting it in a pie pan thing, and push the round hollow thing totally underwater, then measure the amount of water that is in the pie pan.

MASS it. then fill a gradulated cylinder up with room left for the water to go up. the push the object down into the water. I am pretty sure that would be it. because it being hollow wouldn't really affect anything.

Why can't you just put it in one of those big graduated cylinders? they would be more accurate.

those are very good ideas but you have to take into consideration the air in it. the air will change the mass of the object and you dont want the mass of the air you want the mass of the hallow ball only.

So how would we mass it?

You could vaccum seal it somehow.
