Answer 2

Answer:

Step-by-step explanation:

Hope this will help you....

Let radius of sphere =r

And edge of cube =a

Surface area of sphere = surface area of cube

4πr^2=6a^2

(r/a)^2=6/4π

(r/a)^2=3/2π.....(1)

Volume of sphere /volume of cube

4/3r^2/a^3

=4π/3*(r/a)^3

=4π/3*(√3/2π)^3.....(from eq (1))

2√3/2π

√4*3/2π

=√6/π

Volume of sphere : Volume of cube

=√6:√π
