Trent has at least 30 cubes.

Step-by-step explanation:

ali drove 268 miles using12 gallons of gas at this rate how many miles would he drive using 9 gallons of gas
Semenov [28]

Divide total miles driven by the total amount of gas used to find the number of miles per gallon.

Then multiply that by the number of gallons you want to find out:


268 miles / 12 gallons = 22.333 miles per gallon.

22.333 miles per gallon x 9 gallons = 201 total miles.
