    Answer:

    60 dollars.-

    Explanation:

    1 meter = 3.28 feet

    1 square meter = 3.28^2 feet^2

    1 square meter = 10.7584 square feet.

    20 square meters = 10.7584 * 20 = 215.168 square feet.

    The area to be painted is 108.0 * 10.0 = 1080 square feet

    The number of cans of paint needed = 1080/215.168

    The number of cans of paint needed = 5.09 cans

    Even with so little above 5, you have to round up. So it is 6 cans of paint needed.

    1 can of paint costs 10 dollars.

    6 cans of paint costs 6 * 10 = 60 dollars
