Those \"5 steps for problem solving\" are a mystery to me.
\n" ); document.write( "I solve problems my own way, using my own reasoning and not a pre-set recipe.
\n" ); document.write( "I believe that using recipes is the wrong way to teach math.
\n" ); document.write( "
\n" ); document.write( "The volume of a rectangular right prism can be calculated as
\n" ); document.write( "Volume = length X width X height
\n" ); document.write( "If the volume (V, in cubic feet) has to be at least 72 cubic feet, and the height (or thickness) of the slab is x feet,
\n" ); document.write( "\"V%3E=72\" and \"V=12%2A8%2Ax\" can be combined to get
\n" ); document.write( "\"12%2A8%2Ax%3E=72\" --> \"x%3E=72%2F8%2F12\" --> \"x%3E=3%2F4\"
\n" ); document.write( "So the concrete slab should be at least 3/4 of a foot (9 inches) thick.
\n" ); document.write( "
\n" );
