Find the volume of the dirt that needs to be hauled away.
\n" ); document.write( "Then find the number of truckloads to haul the dirt.
\n" ); document.write( "Multiply the number of truckloads by cost per truckload to get the total cost.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Volume
\n" ); document.write( " $\"V=42%2A24%2A9=9072\"$ cubic feet
\n" ); document.write( "Convert from cubic feet to cubic yards.
\n" ); document.write( " $\"1\"$ yd = $\"3\"$ ft
\n" ); document.write( " $\"1%5E3\"$ yd^3= $\"3%5E3\"$ ft^3
\n" ); document.write( " $\"1\"$ yd^3= $\"9\"$ ft^3
\n" ); document.write( " $\"V=9072%2F9=1008\"$ yd^3
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Each truck holds $\"8\"$ yd^3.
\n" ); document.write( "So the number of trucks equals total volume divided by truck volume.
\n" ); document.write( " $\"N=1008%2F8=126\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Each truck cost $5.
\n" ); document.write( " $\"Total=5%28126%29=630\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "To remove the dirt, the contractor needs to pay $630. \n" ); document.write( "
