Question 292024
Let the side of box be x

the volume of box will be x^3

The diameter of the ball will be x

so radius will be x/2

the volume of ball will be 4/3 * pi*(x/2)^3

= 4/3* pi*x^3/8

4/3*1/8 +pi*x^3

1/6 *pi^x^3

the ratio of the volume of ball to box will be 

1/6 * pi* x^3  / x^3

=1/6*3.14 *100

52.33 % of the volume of box
