Answer :

Given,

Dimensions of cuboid l = 12cm

b = 11cm

h = 9cm

Diameter of sphere (d) = 3mm

r = = 1.5mm

r = 0.15 cm

When we melt any object, and convert it into another then the volume of both the object will be same.

So,

Volume of cuboid = n × volume of sphere

n = no. of sphere

l × b × h =

12 × 11 × 9 =

n =

n = 84000
