Answer:
- <em><u>3.30 × 10⁶ kg</u></em>
Explanation:
The form of the pool may be approximated to a reactangular prism with height equal to the average depth of water.
<u>1) Dimensions:</u>
- Length: 44.6 m
- Wide: 27.6 m
- Height: 8.80 ft
<u>2) Volume formula</u>
- V = length × width × height
<u>3) Unit conversions</u>
Convert 8.80 ft to meters:
- 1 ft = 0.3048 m ⇒ 1 = 0.3048 m/ft
- 8.80 ft × 0.3048 m/ft = 2.68 m
<u>4) Volume calculation</u>
Substitute the numbers in the formula:
- V = length × width × height = 44.6 m × 27.6 m × 2.68 m ≈ 3,298.97 m³ ≈ 3,300 m³ (it is rounded to three significant digits)
<u>5) Mass of water:</u>
- Density = mass / volume ⇒ mass = density × mass
- Density of water = 1,000 kg / m³
- mass = 3,300 m³ × 1,000 kg / m³ = 3,300,000 kg
<em><u>6) Scientific notation</u></em>
Choose the correct number of significant figures:
- Since the three given factors have 3 significant figures, the correct number of significant figures of the volume and the mass is 3.
The mass must be expressed as a power of ten. The mantissa contains only the significant digits, and the number before the decimal point can only have one digit 1 through 9.
- 3,300,000 kg = 3.30 × 10⁶ kg
Mass and acceleration are needed to find the net force.

Explanation: A molecular model is a plastic model with interchangeable balls. Represents molecules and their processes.
The creation of mathematical models of molecular properties and behavior is molecular modelling, and their graphical depiction is molecular graphics, but these topics are closely linked and each uses techniques from the others.
