outer length of box = 80 cm
outer width of box = 65 cm
outer height of the box = 45 cm
Since thickness of wood is 2.5cm
inner length of box = 80 -2 x 2.5 = 75 cm
inner width of box = 65 - 5 = 60 cm
inner height of box = 45 - 5 = 40 cm
Capacity of the box = 75x60x40 = 180,000 cm^3
Volume of wooden part = 80 x 65 x 45 - 75 x 60 x 40 = 54,000 cm^3
Weight of 100 cm^3 of wood = 8g
weight of 54,000 cm^3 of wood will be 8/100 x 54,000 = 4320g
