\n" ); document.write( "how much cardboard do you need
\n" ); document.write( ":
\n" ); document.write( "Find the surface area of the closed box
\n" ); document.write( "S.A. = 2(10*5) + 2(10*5) + 2(5*5)
\n" ); document.write( "S.A. = 100 + 100 + 50
\n" ); document.write( "S.A. = 250 sq/cm for the box
\n" ); document.write( ":
\n" ); document.write( "Let a = amt of cardboard required
\n" ); document.write( "then
\n" ); document.write( ".1a = wasted amt
\n" ); document.write( ":
\n" ); document.write( "a = .1a + 250
\n" ); document.write( "a - .1a = 250
\n" ); document.write( ".9a = 250
