One quart serves 2 coatings on 9X10 = 90 ft^2.
\n" ); document.write( "=> one quart serves one coating on 180 ft^2
\n" ); document.write( "The area of the required wall is 10X12 = 120 ft^2, and one coating is required on it.
\n" ); document.write( "180 ft^2 comsumes 1 quart
\n" ); document.write( "=> 1 ft^2 consumes 1/180 quart
\n" ); document.write( "=> 120 ft^2 consumes 120/180 quart = 2/3 quart
\n" ); document.write( "
\n" );
