I NEED HELP WITH THE 4 QUESTIONS ON THE BOTTOM ......... Step 1: The Family Pool http://tinypic.com/r/1h4jmh/6 Volume of Pool V = lwh V = 24 • 9 • 7 V = 1512 ft3 Amount of Pool Liner ...

PGroot Answered:

1. The dog's pool volume is 23.625 ft3, the family pool is 1512 ft3, exactly corresponding to the product of the dimensions.

2. The diffference in volume when filled to the top 1512 ft3 and filled to 6 inches of the top 1404 ft3 so the difference is 108 ft3.

3. The pool liner needs to include one base, so it is neither lateral area nor surface area.

4. steps in the pool would take up volume, reducing the volume of water.

Adding steps would reduce the area on the bottom of the pool but the same amount would cover the tops of the steps. It would reduce the area on one side but the same amount would cover the risers of the steps. There would be additional area of liner for the sides of the steps.
