Maria is designing a series of stationery trays for holding paper and envelopes.
Each tray starts as a rectangular sheet of metal from which identical squares are cut from the four
corners. The resulting rectangular flaps are then folded up and welded to produce an open-topped
rectangular tray. What size square should Maria cut from a rectangular sheet of metal 15 cm by 25 cm
in order to produce a tray with a volume of 476 cm3? Round to the nearest hundredth of a
centimetre, if necesary.
