Conversions and Volume

  1. Sep 17, 2009 #1
    1. The problem statement, all variables and given/known data
    A sphere has a radius of 5 m. How many 5cm diameter spheres can it contain?


    2. Relevant equations
    Volume of a sphere= 4/3π r^3


    3. The attempt at a solution
    5m=500 cm

    volume of large sphere/ volume of small sphere
    4/3π (500)^3/ 4/3π (2.5)^3

    =8,000,000 spheres

    This answer doesn't seem reasonable. What am I doing wrong?
