## Homework Statement

Estimate the number of ping pong balls (of radius 2cm) that would fit into a typical-sized room (without being crushed). A typical room is 17ft x 17ft x 7ft.

## Homework Equations

none

## The Attempt at a Solution

I tried a couple things:

1. After converting all dimensions to cm, I tried to see how many cubes of edge length 4cm would fit in the room.

2. I used a "spherical packing" method where I found the total volume of the room and multiplied it by .70.

Any help would be greatly appreciated :)
