Question

. A Cube of side 4 cm contains a sphere touching its side. Then the Volume of the gap

in between is.​

Answer 1

Here , Cube of side 4cm

it means diameter of sphere would be also 4 cm

r = 4/2 = 2 cm

volume of cube = side³

= 4³

= 64cm³

now , volume of sphere = (4/3)π.r³

= (4/3)×(22/7)× 2³

=(88/21)×8

= 704/21

volume of remaining part =

64-(704/21)

= (1344 - 704 )/21

= 640/21cm³
