l=60cm
b=45cm
h=32cm

Volume=60×45×32==>86400cm³

Volume regarding thickness
Thickness will be double =2.5×2=5

l=60-5cm== >55cm
b=45-5cm==>40cm
h=32-5cm==>27cm

Then,
Volume=55×40×27==>59400cm³

Volume of wood
=Volume of original rectangular box-Volume after thickness subtracted.

==>86400-59400
==>27000cm³

volume of wood = surface area of box × Thickness of wood
= 2(60*45+45*32+32*60)*2.5 = 30300cm^3

Volume of box = 60*45*32= 86400 cm^3
