One cubic meter of granite has a mass of 2.70E3 kg, and one cubic meter of gold has a mass of 1.93E4 kg. Find the radius of a granite sphere whose mass is the same as that of a gold sphere of radius 1.07 cm.
Any help is appreciated!!

The masses are the same?
densitygold*PI*4/3*1.07^3 = densityrock*PI*4/3*x^3
solve for x. I will be happy to critique your work.
