A storage locker measures 8 feet wide, 12 feet deep, and 9 feet high. The monthly rental price for the locker is $3.60 per cubic yard. How much does it cost to rent the locker each month?

In yards, the dimensions are (8/3), (12/3) = 4, and (9/3) = 3. The volume of the locker is the product of these dimensions.

Then the rent is

($3.60/yd³) * (8/3 yd) * (4 yd) * (3 yd) = $115.20

The rental cost each month is $115.20.
