Given the largest side of cube as 7cm.
largest side of cube id diameter d =7
radius r =d/2
=7/2
=3.5
volume of the sphere = 4/3 πr3
= 4/3 *(22/7)*(3.5)3
= 4/3 *(22/7)*(3.5)*(3.5)*(3.5)
=179.66
volume of sphere is 179.66 cm3
Total surface area of sphere=4πr²
=4*22/7*(3.5) ²
=4*22/7*3.5*3.5
=154
Hope it helps u
