So to find the answer to this equation, we need to find the Volume. Simply multiple the measurements given. Notice 4.40 ft for the <u>average depth</u>, we need to convert this to metres (3.28ft in 1m) first (for scientific notation and proper units):
4.4ft/3.28ft = 1.3m (about)
Now we can find the entire volume of the pool:
1.3m * 59.8m *41.4m = 3,218.4m^3
Now, since there are 1,000 liters in a cubic metre, you would multiple the cubic meters by this number.
3,218.4m^3 * 1,000L = 3,218,400L
Since you asked in mL, multiple this by 1,000 again.
3,218,400L * 1,000 = 3,218,400,000mL
This is how you do the conversion. Now that you have to convert to scientific notation. Since you seem to follow the sig-figs to the nearest tenth, I will put it into that.
This is your final answer: 3.2 × 10^9
<em>(Move over the decimal of </em>3,218,400,000<u>.</u>0<em> over 9 times to the left, resulting in 10^9)</em>
I hope I have helped you.
