You can put this solution on YOUR website!
Density would help.
\n" ); document.write( "The forty pound bag delivers a volume of \"10%281%2F12%29=5%2F6\" cubic feet of soil.
\n" ); document.write( "You can use the density as \"40%2F%285%2F6%29=240%2F5=highlight_green%2848%29\" pounds per cubic foot.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The description for the question part is missing a word, believed to be \"cubic\".
\n" ); document.write( "You must mean, how many bags to fill 200 CUBIC meters by 4 centimeters. You must do some
\n" ); document.write( "unit conversions.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "\"highlight_green%28%28200%2A0.04%2A10%5E6%29%2F%28%282.54%29%5E3%2A12%5E3%29%29\" \"highlight_green%28feet%5E3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "What you really need to use now is just this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is 282.5 cubic feet, allowing for four significant figures (probably more than justifiable).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Again, 1 bag of topsoil is \"5%2F6\" cubic feet. How many \"5%2F6\" cubic feet contained in 282.5 cubic feet?
\n" ); document.write( "That is how many bags of the topsoil.
\n" ); document.write( "\"282.5%2F%285%2F6%29\"
\n" ); document.write( "\"6%28282.5%29%2F5\"
\n" ); document.write( "\"highlight%28339%29\" bags\r
