to find the capacity
to find the inner volume subtract the dimentions by (2*2)=4
therefore capacity= inner volume= 50*36*12= 15600
so volume of wood= outer volume-inner volume
=54*30*16-50*26*12
=24000-15600
=8400cm^3

Answer:
18200cm³ , 7720 cm³
Step-by-step explanation:
External dimensions
Length 54 cm
Breadth 30 cm
Height 16 Cm
Internal dimensions
Length 54 -(2+2)=50 cm
Breadth 30 -(2+2) =26 cm
Height 16 -2 = 14
As the box is open from top we subtract only the lower wood thickness
Capacity of the box = internal volume
= 50*26*14= 18200 cm³
External volume = 54*30*16
=25920 cm³
Volume of the wood =external volume - internal volume
=25920-18200
=7720cm³
