5gallon = 0.6685 cubic feet how many gallon is 1 cubic foot?

7.48 gallons. Vote me brainliest

7.479 is the answer, however there is a bunch more decimals following it. You can do these problems by diving the .6685 by 5, giving you the amount for 1 gallon which should be .1337 Then you can divide 1 (the cubic foot) by .1337, and you'll get the answer. Mark as brainliest if this helped you at all please :).

Step-by-step explanation:

The fifth term is just the next term. One possible answer can be obtained by looking at the differences in the first four terms: 2 (=3–1), 4 (=7–3) and 8 (=15–7). They are 2^1, 2^2 and 2^3. I would say the fifth term is 15+2^4 = 15 + 16 = 31.
