Question

How many spherical balls can be made out of a solid cud’s of lead whose edge measures 66 cm and each ball being 3 cm in radius

Answer 1

Answer: 2542app

Step-by-step explanation:

Edge of cube= 66cm

Volume of cube= a^3=66×66×66=287496

Radius of spherical ball=3cm

Volume of spherical ball=4/3πr^3

=4/3×22/7×3×3×3=113.1

No of balls =287496÷113.1=2542 app
