Question

how many sperical balls each 7cm in diameter can be made out of a solid lead cube whose edge is 66cm​

Answer 1

Answer:

3,65,904 balls

Step-by-step explanation

volume of cube=66x66x66

volume of spherical ball= 4/3x22/7(pi)x7x7x7

number of balls=volume of cube/volume of spherical ball

                         = 66x66x66/{4/3x22/7x7x7x7}

                         = 3,65,904 balls

hope it is correct
