Volume of cube=s^3
s=6
V of cube=216
Volume of sphere=(4/3)pi(r^3)
r=3, if diameter=6
(4/3)(pi)(3^3)
V of sphere=36pi
Vcube-Vsphere=102.9026645
=103

Answer:

103 cube inches

Explanation:

Since sphere fits snugly inside a cube therefore diameter of sphere will be equal to side of the cube [ which is given to be 6 inches ]

diameter = 6 inches

radius =
(diameter )/(2)

=
(6 )/(2)

= 3 inches

Volume of the sphere is given by
(4)/(3)\pi r^3

here r =3 inches

therefore volume is=
(4)/(3)\pi 3^3

= 36 pi

= 36 ( 3.142)

= 113.097 cube inches

Volume of Cube = side x side xside = 6x6x6 = 216 cube inches

Volume of space between sphere and cube = 216 - 113.097= 102.9 cube inches , nearest whole number is 103 cube inches
