Question

What steps would you take to determine the density of a baseball?

Answer 1

You need (i) mass of the baseball, and (ii) volume of the baseball.

Explanation:

So record an accurate mass. Next get a pair of calipers and accurately measure the diameter of the baseball, and halve this value to get the radius, `r`; the volume of the baseball is (to a first approx.) `4pir^3`.

`"Density of the baseball "=("Mass")/("Volume")`

When you do the experiment, would you please post the results here? I played a lot of cricket in my youth, and I know for a fact that leather bound cricket balls float; I would be interested to compare their density to that of the baseball.
