156. A solid metal sphere has a volume of 4.2 ft}. The mass of the sphere is 155 lb. Find the density of the metal
sphere in grams per cubic centimeter.

The answer is

Explanation:

To find the density of the sphere we use the formula

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

We have the final answer as
