Answer :

There are 693 cubic inches in 3.0 gallons.


To find the number of cubic inches in 3.0 gallons, we need to use a conversion factor.

One gallon is equal to 231 cubic inches (according to the US system of measurement), so we can set up the following proportion:

1 gal / 231 in³ = 3 gal / x

Solving for x, we can cross-multiply and get:

x = (3 gal)(231 in³ / 1 gal)

x = 693 in³

Therefore, there are 693 cubic inches in 3.0 gallons.

Since the original measurement has only one significant figure (3), the final answer should also have only one significant figure (693).
