How do I find the LENGTH of a CUBOID with the width of 12mm, height of 6cm and the Total Surface Area of 468cm^2
\n" ); document.write( ":
\n" ); document.write( " 2(L*W) + 2(L*H) + 2(W*H) = S.A.
\n" ); document.write( ":
\n" ); document.write( "2(12L) + 2(6L) + 2(12*6) = 468
\n" ); document.write( ":
\n" ); document.write( "24L + 12L + 2(72) = 468
\n" ); document.write( ":
\n" ); document.write( "36L + 144 = 468
\n" ); document.write( ":
\n" ); document.write( "36L = 468 - 144
\n" ); document.write( ":
\n" ); document.write( "36L = 324
\n" ); document.write( "L = \"324%2F36\"
\n" ); document.write( "L = 9 mm is the length
\n" ); document.write( ":
\n" ); document.write( "You can check solution in the original Surface area equation
\n" ); document.write( "
