Question

find the ratio of surface area and volume of the cube of unit edge​

Answer 1

ANSWER

Let the radius of the sphere which fits exactly into a cube be r units.

Then,

Length of each edge of the cube =2r units

Let V1 and V2 be the volumes of the cube and sphere respectively. Then,

V1=(2r) 3 and V2 =34

πr 3

V2 V1 = π6

V1:V2

=6:π
