1. Answer:

   Given outer length =30 cm

   Outer breadth =20 cm

   Outer height =80 cm

   Outer volume = length × breadth × height

   =30×20×80=48000cm

   Thickness of wooden box, w=1 cm

   Inner length =l–2w=30–2=28 cm

   Inner breadth =b–2w=20–2=18 cm

   Inner height =h–2w=80–2=78 cm

   Inner volume =28×18×78=39,312‬cm

   3

   Volume of wood used = outer volume – inner volume

   =48000−39,312‬=8,688cm
