The volume of a large sphere is twice the volume of a small sphere.
By what factor do you need to multiply the radius of the small sphere to equal the radius of the large sphere?
:
a = the required factor

= 2()
divide both sides by

divide both sides by r^3
a^3 = 2
a = (the cube root of 2)is the factor to multiply the radius to double the volume
