l = 20 m, b = 15 m, and h = 6 m
\n" ); document.write( " Capacity of the tank = lbh = (20 × 15 × 6) m3
\n" ); document.write( " = 1800 m3
\n" ); document.write( "Water requirement per person per day = 150 litres
\n" ); document.write( "4000 * 150/1000 = 600 m ^3
\n" ); document.write( "1800/600 = 30 days
\n" ); document.write( "
\n" );
