Question

The surface area of cube is equal to the surface area of a sphere .Find the ratio of volume of cube to that of the sphere​

Answer 1

Answer:

Since,

$6a = 4\pi {r}^{2}$

Hence,

$\frac{ {a}^{3} }{\frac{4}{3} \pi {r}^{3} } = \frac{ {a}^{2} }{2r}$

Answer 2

Answer:

Answer:

Since,

6a = 4\pi {r}^{2}6a=4πr

2

Hence,

\frac{ {a}^{3} }{\frac{4}{3} \pi {r}^{3} } = \frac{ {a}^{2} }{2r}
