area of each wall is \"12%2A24=240\" square feet.
\n" ); document.write( "area of four walls together is \"240+%2B+240+%2B+240+%2B+240+=+960\" square feet.
\n" ); document.write( "two coats on each wall would be similar of painting \"960%2A2=1920\" square feet.
\n" ); document.write( "area of roof is \"10%2A10=100\" square feet (double coat on roof is not mentioned).
\n" ); document.write( "area of each wall with two coats + area of roof with a single coat = \"1920%2B100=2020\".\r
\n" ); document.write( "\n" ); document.write( "A gallon of paint can cover \"512\" square feet so, four gallons of paint would be needed to cover \"512%2A4=2048\" square feet.
\n" ); document.write( "paint which can cover \"2048-2020=28\" square feet will be left.
\n" ); document.write( "
