volume is length x width x depth\r
\n" ); document.write( "\n" ); document.write( "to find the depth on this, we will use the pathagorias theorm for triangle leg lengths
\n" ); document.write( "a^2 + b^2 = c^2\r
\n" ); document.write( "\n" ); document.write( "we have our a length and c length, lets solve for b\r
\n" ); document.write( "\n" ); document.write( "7^2 + b^2 = 10^2\r
\n" ); document.write( "\n" ); document.write( "49 + b^2 = 100\r
\n" ); document.write( "\n" ); document.write( "subtract 49 from both sides\r
\n" ); document.write( "\n" ); document.write( "b^2 = 51\r
\n" ); document.write( "\n" ); document.write( "b = 7.14\r
\n" ); document.write( "\n" ); document.write( "so, our height is 7.14, or the square root of 51\r
\n" ); document.write( "\n" ); document.write( "lets plug our newfound number into the equation and find the volume...\r
\n" ); document.write( "\n" ); document.write( "7 x 6 x 7.14 = 299.88 cubic feet
\n" ); document.write( "
\n" );
