Find the cost of painting the outer surface of 24 oil containers at $2.50 per square meter, the dimensions of each container being 60 centimeters by 40 centimeters by 56 centimeters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the dimensions of the container are 60 cms by 40 cms by 56 cms\r
\n" ); document.write( "\n" ); document.write( "= 0.6 meters by 0.4 meters by 0.56 meters\r
\n" ); document.write( "\n" ); document.write( "There are 8 faces in a cuboid 4 faces will have same area. The other four faces will have same arae.\r
\n" ); document.write( "\n" ); document.write( "let area of one face be 0.6 * 0.4 = =0.24 sq. meters\r
\n" ); document.write( "\n" ); document.write( "The other face will be 0.4* 0.56 = 0.22 sq. meters\r
\n" ); document.write( "\n" ); document.write( "The total surafce area of the can will be \r
\n" ); document.write( "\n" ); document.write( "4 * 0.24 + 4* 0.22 sq.. meters\r
\n" ); document.write( "\n" ); document.write( "0.96 + 0.88 sq. meters = 1.84 \r
\n" ); document.write( "\n" ); document.write( "Number of containers = 24 , cost of painting per container = $2.50\r
\n" ); document.write( "\n" ); document.write( "Toal cost = 240 * 2.5 * 1.84 $ 1104 \r
