Question

how many spherical balls of radius 2.1cm can be formed from a cuboid of dimensions 88,42,21​

Answer 1

Answer:

Step-by-step explanation:

onvert all the values in cm to m.

let n be the number of balls formed. n*volume of small lead ball = (V1+V2+V3)

n*4/3πr^3=4/3π(r1^3+r2^3+r3^3)

n*4/3*22/7*2.1*2.1*2.1=4/3*22/7*(88*88*88+44*44*44+21*21*21)

n*9.261=681472+85184+9261

n*9.261=775917

n=775917/9.261

n=83783.28

n is approximately equal to 83783

therefore 83783 lead balls can be made of radius 2.1cm
