An open box is made from a 30 cm by 58 cm piece of tin by cutting a square from each corner and folding up the edges. The area of the resulting base is 348 cm². What is the length of the sides of the squares?
\n" ); document.write( "

Let one side of one of the square to be cut off, be S
\n" );
document.write( "Length of each side of tin needs to be decreased by: 2S cm
\n" );
document.write( "We then get: (30 - 2S)(58 - 2S) = 348
\n" );

document.write( "Using the quadratic equation formula, or completing the square, S, or length of a side of one of the squares =  cm \n" );
