## Homework Statement

Today In class(1st day of physics) the teacher paired us up and told us to figure out how to make a lead ball float in water. The ball has a radius of 1 meter and is made of lead. To make it float we can hollow it out and fill the empty space with air. For this problem we need to figure out how thick the wall of the sphere needs to be so the lead sphere floats.

## Homework Equations

All I know is that density somehow plays into it.

## The Attempt at a Solution

None so far.
