Find out the internal dimensions:
length = 86 - 3 -3 = 80 cm
width = 60 - 3 -3 = 54 cm
height = 45 - 3 = 42 cm (since there is no lid)
therefore capacity = 80*54*42 = 181,440 cubic cm
volume of wood = total volume - capacity = 86*60*45 - 181440 = 50760 cubic cm

bottom (internal) = (86 - 6) * (60 - 6) = 4320
height (internal) = (45 - 3) = 42
volume (internal) = 4320 * 42 = 181440 cm^3
b = 86 * 60 * 3 = 15480
s1 = (45 - 3) * (86 - 6) * 3 = 10080
s2 = (45 - 3) * 60 * 3 = 7560
volume (wood) = b + 2(s1) + 2(s2) = 50760 cm^3

Internal volume:
v = (86-6)*(60-6)*(45-3)
v = (80)*(54)*(42)
v = 181440 cm³
v = 181.44 liters
External volume:
V = 86*60*45
V = 232200 cm³
Volume of wood:
Vw = 232200 - 181440
Vw = 50760 cm³
Vw = 50.76 liters

Is 45 the depth? if so:-
external volume = 86 x 60 x 45 cu.cm. = 232,200
internal volume = 80 x 54 x 42 cu.cm. = 181,440
difference = volume of wood = 50,760
