Question 757976
The volume of each sphere = {{{(4/3)*pi*r^3}}}
Three spheres have a total volume of {{{4*pi*r^3}}}
The volume of liquid wax in the cylinder will be {{{pi*r^2*h}}} where h = the height
We can equate the two volumes and solve for h:
{{{4*pi*r^3 = pi*r^2*h}}}
Cancelling {{{pi*r^2}}} from both sides leaves {{{h = 4r}}}
