Are of the floor: 15x20
\n" ); document.write( " = 300 sq.ft\r
\n" ); document.write( "\n" ); document.write( "For the first coat: 1 gallon covers 200 sq. ft so that would be one gallon.
\n" ); document.write( "Now 300-200= 100. We're left with 100 sq. ft. 1/2 gallon for that.
\n" ); document.write( "That makes 1.5 gallon for the first coat.\r
\n" ); document.write( "\n" ); document.write( "For the second coat: 1 gallon of varnish covers 300 square feet on the second coat so we only need 1 gallon.
\n" ); document.write( "
\n" ); document.write( "Now we add both: 1.5+1=2.5 gallons required in total.
\n" ); document.write( "
\n" );
