A flat, square piece of cardboard is used to construct an open box by cutting out squares (measuring 1 foot by 1 foot) from the corners and folding up the resulting edges. If a particular box has a volume of 16 cubic feet, what are the dimensions of the original piece of cardboard? need it pls :( in 2 hours PLS! </SPAN>\n" );
