उत्तर

In the given problem, the largest sphere is carved out of a cube and we have to find the volume of the sphere.

Side of a cube = 6 cm

So, for the largest sphere in a cube, the diameter of the sphere will be equal to side of the cube.

Therefore, diameter of the sphere = 6 cm

Radius of the sphere = 3 cm

Now, the volume of the sphere =  `(4/3)pi r^3`

`=(4/3) pi (3)^3 `

= 36 π

Therefore, the volume of the largest sphere inside the given cube is  36 π .
