Answer:

Thats all you really need to answer, it doesnt ask for you to explain it or anything.
So you already have the volumes, so you just need to fill out the chart, right?
Pool | Length | width | depth | volume
kiddie pool | 15 | 15 | 2 | 450
Lap Pool | 25 | 15 | 5 | 16,875
Diving pool | 30 | 20 | 5 | 7500
Total: 24,825
7^{2} + 7^{2} = C^{2}
49 + 49 = C^{2}
98 = C^{2}
9.8 ≈ C
10 ≈ C
C = hypotenuse
