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?
