You can put this solution on YOUR website!
You can solve this in 2 ways, we'll go to the faster one first:
\n" ); document.write( "\"A=6\"*\"%28V%29%5E%282%2F3%29\"
\n" ); document.write( "Divide the whole eqn by 6 then multiply exponent ^3/2 the whole eqn so we can cancell the exponent of the unknown, \"V\"
\n" ); document.write( "\"cross%2812%292%2Fcross%286%291\"=\"cross%286%29%2Fcross%286%29\"*\"V%5E%282%2F3%29\"
\n" ); document.write( "\"2%5E%283%2F2%29\"=V^(2/3)(3/2)=\"V%5E%286%2F6%29=V\", oks
\n" ); document.write( "Continuing,
\n" ); document.write( "\"V=2.8284271\" -----------> for the Volume
\n" ); document.write( ".
\n" ); document.write( "For other eqn, we can go for the formula for Area since it is given, then go for the formula in finding the volume:
\n" ); document.write( "\"A=6s%5E2\", s=sides of the cube
\n" ); document.write( "\"12%2F6+=+s%5E2\", \"s=sqrt%282%29\",\"s=1.4142136\"
\n" ); document.write( "For the Volume,
\n" ); document.write( "\"V=s%5E3=1.4142136%5E3\"
\n" ); document.write( "\"V=2.8234271\" -----------> for the Volume
\n" ); document.write( "Thank you,
