Problem: A thief plans to steal a gold sphere with a radius of 28.5 cm from a museum. If the gold has a density of 19.3 g/cm3, what is the mass of the sphere in pounds? [The volume of a sphere is V = (4/3) r3.]

FREE Expert Solution

We are asked to calculate the mass of the sphere in pounds. 


Calculate volume: 

V =43r3V =43(28.5 cm)3

V= 30,865.5 cm3
