swimming pool measuring 15m by 20m by 1.2m\r
\n" ); document.write( "\n" ); document.write( "volume of swimming pool = 15*20*1.2\r
\n" ); document.write( "\n" ); document.write( "=360m^3\r
\n" ); document.write( "\n" ); document.write( "1 m^3=1000 liters\r
\n" ); document.write( "\n" ); document.write( "360 m^3= 360000 liters\r
\n" ); document.write( "\n" ); document.write( "Let number of taps be x
\n" ); document.write( "each minute 50x liters is filled\r
\n" ); document.write( "\n" ); document.write( "in 1 hour\r
\n" ); document.write( "\n" ); document.write( "the pool fills 50x * 60 liters\r
\n" ); document.write( "\n" ); document.write( "= 3000x liters\r
