Question 683328
A wooden cube of side 15cm is used to make a spherical ball. Work out the volume of wood that must be cut from the cube to make a ball with the largest possible radius.
---------------
The largest diameter = side length = 15 cm
r = 7.5 cm
Vol of cube = 15^3 cc
Vol of sphere = {{{4*pi*r^3/3}}} cc
Wood removed is the difference
