Yo has to factor since we assume that

if you have xy=0, x and y=0

7n^2-48n+36=0

trial and error

(7n-6)(n-6)=0

set each to zero

7n-6=0

add 6

7n=6

divide 7

n=6/7

n-6=0

add 6

n=6

n=6/7 or 6

the volume of the ball is 523.3. since the formula for the volume is 4/3*pi*r^3, the radius of ball is 5 in. Therefore, the diameter of the ball and the height of the box is 10.
