Answer:
0.6 cm
Step-by-step explanation:
volume of sphere=4/3*pi*(r^3)
vol.=4/3*22/7*0.00375
vol=0.014
total volume=0.014*64=0.896
radius of greater cube=0.6

Answer:
Step-by-step explanation:
Since they're being melted we need to find the volume.
Voleme of one tiny sphere
=4/3pie r^3
=4/3×22/7×0.15×0.15×0.15
=0.099/7
=0.014
Volume of 64 such spheres or One big sphere
=0.014×64
=0.896
Radius of sphere
0.896=4/3 pie r^3
0.896=4/3×22/7×r^3
0.896×3/4×7/22 = r^3
4.704/22= r^3
0.216(approx.) =r^3
0.6=r^3
