__GIVEN ;-__

**⇒ Ratio of their volumes = ?**

TO FIND ;-

TO FIND ;-

**⇒ a = d**

SOL ;-

In the question it is given that the height of the sphere and cube are same - so this mean that their side of the cube will be also equal to the diametre of the sphere,

SOL ;-

In the question it is given that the height of the sphere and cube are same - so this mean that their side of the cube will be also equal to the diametre of the sphere,

**⇒ Volume of sphere : Volume of cube**

__So to find out the answer for this sum , we need to use the given formula to find out their ratio - that is -__

**⇒ (4/3) × π × r³ : a³**

**⇒ (4/3)× π× r : (2r)³**

⇒ (4/3) × π × r³ : 8 × r³

⇒ (4 /3) × (22/7) : 8

⇒ (88 /21 ) : 8

⇒ (11/21) : 1

**⇒ 11 : 21**

So the answer is 11 : 21

So the answer is 11 : 21
