Algebra.Com's Answer #125594 by checkley77(12844)![]() ![]() ![]() You can put this solution on YOUR website! The final surface area of the box is: \n" ); document.write( "10*5=50 for the base. \n" ); document.write( "2*10*5=100 for the 2 long sides. \n" ); document.write( "2*5*5=50 for the 2 short sides. \n" ); document.write( "50+100+50=200 cm^2 for the total surface. \n" ); document.write( ".10*200=20 cm^2 will be wasted? \n" ); document.write( "Graphing the problem this answer doesn't make sense. By cutting 4 5x5 corners this accounts for 100 cm^2 wasted out of a 15x20=300 cm^2 piece of cardboard. \n" ); document.write( "Here the waste is 100 cm^2 out of 300 cm^2 (33%) original size or 100 cm^2 out of 200 cm^2 (50%) for the box. \n" ); document.write( " |
