Answer:
395 cc
Step-by-step explanation:
In the box ,
Length = 20 cm
Breadth = 12 cm
Height = 6 cm
Width of wood = 0.5 cm
So , length without wood = 19.5 cm
Breadth without wood = 11.5 cm
Height without wood = 5.5 cm
Now ,
Volume of box with wood = 20×12×6 cc
Volume of box without wood = 19×11×5 cc
Volume of wood in the box = 20×12×6 - 19×11×5 cc
=1440 - 1045 cc
= 395 cc (Ans)
