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
