# A solid piece of

Given: Dimension of cuboid (49 cm × 33 cm × 24 cm)

Volume of cuboid is : length × breadth × height

Volume of Solid Sphere is : × π × r3 (here r is radius of the sphere)

Let v1 be the volume of given cuboid.

v1 = 49 cm × 33 cm × 24 cm = 38808 cm3

Let v2 be the volume of Solid Sphere.

We know that when a object is moulded from one shape to other its volume does not change.

v1=v2

That is,

38808 = × π × r3

r3 = × 38808

r3 = 9261 r = 9261 = 21

r = 21cm

That is, radius of the Solid sphere = 21cm
