Suppose that eh volume of a ball is equal to Pie/6 times the volume of a cube What is the ration of the surface area of the ball to that of the cube?
Pet peeve warning!!
It's spelled "pi" not "pie."
Pet peeve over.
Okay. We know that .
We also know that
(Where "s" is the side of the cube.)
So, solve for r:
Now sub in the relation for into the equation and take the ratio.
