find the number of steel ball bearings, each of diameter .7cm, that can be made from 1 kg steel, given that 1 cube of steel weighs 7.85 g.
------------
If you mean 1 cc (cubic cm) of steel weighs 7.85 gm:
-------
r = 0.35 cm
Vol of each ball = cc
----------
1 kg of steel = 1000/7.85 grams ( = volume in cc)
------
# of balls = (1000/7.85)/Vol
----------
