The shortest distance between two points is a straight line and in this case, it's the diagonal that runs from corner to corner. I'm assuming that the spider is traveling from an upper corner to a bottom corner (or vice versa).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It turns out that the diagonal 'd' can be found by the formula \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"a%5E2%2Bb%5E2%2Bc%5E2=d%5E2\" where 'a', 'b', and 'c' are the lengths of the box.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Note: this is analogous to the Pythagorean Theorem.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in this case, a=3, b=1, and c=3 giving us the equation \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%5E2%2B1%5E2%2B3%5E2=d%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"9%2B1%2B9=d%5E2\" Square each value\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"19=d%5E2\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"d=sqrt%2819%29\" Take the square root of both sides. Note: we're only considering the positive square root.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"d=4.359\" Approximate the square root.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the shortest distance that the spider can travel from A to B is roughly 4.359 meters.
\n" ); document.write( "
