You can put this solution on YOUR website!
Not sure of an easy way to do this one other than trial and error or plotting
\n" ); document.write( "Let l be the original length of one side
\n" ); document.write( "After cutting off one inch, the new volume is 294
\n" ); document.write( "So
\n" ); document.write( "\"l%5E2+%2A+%28l-1%29+=+294\"
\n" ); document.write( "\"l%5E3+-+l%5E2+=+294\"
\n" ); document.write( "Let's try 5
\n" ); document.write( "Does 125 - 25 = 294? Nope, too small
\n" ); document.write( "Try 10
\n" ); document.write( "Does 1000 - 100 = 294? Nope too big
\n" ); document.write( "Try 7
\n" ); document.write( "Does
\n" ); document.write( "343 - 49 = 294? Yepper. So the answer is 7.\r
\n" ); document.write( "\n" ); document.write( "You could also plot \"l%5E3+-+l%5E2+=+294\"
