You can put this solution on YOUR website!
Volume of box = length*breadth*height
\n" ); document.write( "Volume of box = 60*30*15
\n" ); document.write( "Volume of box = 27000cm^3
\n" ); document.write( "With one layer of cans laid 3 X 6 = 18
\n" ); document.write( "Breadth/3 = 30/3 = 10cm
\n" ); document.write( "Length/6 = 60/6 = 10cm
\n" ); document.write( "So cans have a diameter of 10cm
\n" ); document.write( "and a radius of 5cm.
\n" ); document.write( "....................
\n" ); document.write( "Volume of cylinder = Pi*r^2*h
\n" ); document.write( "Volume of cylinder = Pi*5^2*15
\n" ); document.write( "Volume of cylinder = 1178.1cm^3
\n" ); document.write( "18 * 1178.1cm
\n" ); document.write( "= 21205.8cm^3 (Occupied by cans)
\n" ); document.write( "Vol. of box - Vol of 18 cans.
\n" ); document.write( "27000 - 21205.8 = 5794.3 (Vol left free)
\n" ); document.write( "Hope this helps.
\n" ); document.write( ":-)
