85732 From a rectangular sheet having dimensions 30 \(\mathbf{c m} \times 80 \mathrm{~cm}\), four equal squares of side \(x \mathrm{~cm}\) are cut at each corner. The remaining sides of the rectangle are folded up vertically so as to form an open rectangular box. Find the value of ' \(x\) ' for which the volume of the box formed is maximum.
