Answer
Given:
Outer length of the box = 12 cm
Outer width of the box = 12 cm
Outer height of the box = 10 cm
Thickness of wood = 1 cm
Internal length = 12 - 1 - 1 cm = 12 - 2 cm = 10 cm
Internal width = 12 - 1 - 1 cm = 12 - 2 cm = 10 cm
Internal height = 10 - 1 - 1 cm = 10 - 2 cm = 8 cm
Volume of internal box = l x b x h
= 10 x 10 x 8 cm3
= 800 cm3
Hence, option 4 is the correct option.
