Question

How many spherical balls can be made out of a solid cube of lead, whose edge measures 66cm and each ball being3 cm in radius

Answer 1

this is your answer
i hope u get it

Answer 2

Answer: There are 2541 spherical balls that can be made.

Step-by-step explanation:

Since we have given that

Radius of each ball = 3 cm

Length of edge of cube = 66 cm

Volume of each ball is given by

$\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times \dfrac{22}{7}\times 3^3\\\\=113.14\ cm^3$

Volume of cube is given by

$66^3=287496$

So, Number of spherical balls is given by

$\dfrac{\text{Volume of cube}}{\text{Volume of ball}}\\\\=\dfrac{287496}{113.14}\\\\\approx 2541$

Hence, there are 2541 spherical balls that can be made.
