Over breakfast today while pondering how to get the large ball down the stairs before it was too heavy to manage - Wayne and I were trying to speculate how heavy it will ultimately be.
So here's the problem:
Today the ball is 20.5 inches in diameter and weighs 40.8 pounds. Assuming consistent density of material, how much will it weigh when the diameter measures 32 inches?
Please email me your solutions.
A winner will be drawn from all the correct answers for a special surprise.
