Hello, Elisa,
This involves several conversions. I don't have the space to upload the table here. I put it on a Google Sheets spreadsheet: https://docs.google.com/spreadsheets/d/1Df6gLC0VLUfVJz7vgaaL0Rr1G2ct3L_WMioVxwYGu_w/edit?usp=sharing
Lines 1, 2,3, 6, and 9: these are known conversion factors.
Line 3: I inverted the conversion factor from line 2. (You can ale=ways invert conversion factors, because the top is essentially the same as the bottom, just in different units).
LIne 5 is converted from line 4,from gallons to liters, using line 1.
Line 7 converts line 5 into ml, using the conversion factor from line 6.
Line 8 derives from the conversion factor 1 ml = 1 cm^3 (Line 2). This is the total volume in cm^3
Line 9 is a known conversion factor and Line 10 is the inverse.
Line 11 is the cube of Line 10, giving us the number of m^3 per cm^3
To get total volume in m^3, multiply Line 8 by Line 11. cm^3 cancels and m^3 remains.
The total volume of 16,000 gallons of water is 60.6 m^3
