Determine:

1. What is the shape and depth of the swimming pool?

2. What is the volume of a tennis ball?

3. Estimate the volume of the swimming pool based on the depth, length, and width of the pool.

4. Calculate the number of balls by dividing the volume of the pool by the volume of the tennis ball.

5. You may wish to subtract balls due to steps in the pool and the gradual upslope of the pool due to the varying depth (but ask first).
