Answer:
The answer is
<h2>0.59 g/cm³</h2>
Explanation:
To find the density of the sphere we use the formula
<h2>
</h2>
To find the density in g/cm³ first convert the mass into grams and the volume into cm³
For the mass we have
155 lb = 70306.82 g
For the volume
4.2 ft³ = 118930.76 cm³
Substitute the values into the above formula
That's
<h2>
</h2>
We have the final answer as
<h3>Density = 0.59 g/cm³</h3>
