3 gallons
4 gallons
5 gallons
14 gallons

Answer 1

5 gallons

Explanation:

Unit conversion (given) : 1 gallon = 3.785 liters

Here, we are given 18 liters.

Then, let the value in gallons be x. We can take the values in proportion.

⇒
`(x)/(1) = (18)/(3.785)`

⇒
`x = (18)/(3.785)`

⇒
`x = 4.75561427`

⇒ x = approximately 5 gallons

Given:

• Liters in 1 gallon

• Cooler holds 18 liters
