A 26 SQUARE INCH PIECE OF CARDBOARD WITH 2 INCHES CUT OUT OF EACH CORNER & FOLDED TO MAKE AN OPEN TOP BOX IS:
\n" ); document.write( "22*22*2=968 IN^3
\n" ); document.write( "---------------------------------
\n" ); document.write( "(X-4)^2+(X-3)^2=X^2
\n" ); document.write( "X^2-8X+16+X^2-6X+9=X^2
\n" ); document.write( "X^2-14X+25=0
\n" ); document.write( "USING THE QUADRATIC EQUATION:\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\" WE GET:
\n" ); document.write( "X=(14+-SQRT[-14^2-4*1*25])/2*1
\n" ); document.write( "X=(14+-SQRT[196-100])/2
\n" ); document.write( "X=(14+-SQRT96)/2

\n" ); document.write( "X=(14+9.8)/2
\n" ); document.write( "X=23.8/2
\n" ); document.write( "X=11.9 FEET IDS THE LENGTH OF THE LADDER.
\n" ); document.write( "PROOF:
\n" ); document.write( "(11.9-4)^2+(11.9-3)^2=11.9^2
