a gallon of paint. covers an average of 20.0m^2 of surface. The paint costs $10.00 per gallon. What is the cost of the paint needed to cover a surface that is 108.0ft long by 10.0ft wide?

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
