Since in this problem, we are dealing with a balloon we can now say that the container or the shape we are dealing with is a sphere. The volume of a sphere is

hence the volume is directly proportional to the radius. The volume increase by a factor of
X would equal 8 and y would equal -7
If a single board measures 1/12 of a meter then it would take 12 boards to make a meter. Since, the stack is 2 meters high. You would multiply 12 and 2 to get 24. There is 24 boards in the stack.
