volume=area*height
792=132*height
height=792/132
height=6
792=132*height
height=792/132

Given length of cuboid = 30cm.
Given breadth of cuboid = 25cm.
Given height of cuboid = 20cm.
External volume of wooden cuboid = 30 * 25 * 20
= 15000cm^3.
Given the thickness of wood all around w = 2cm.
Internal Length of wooden cuboid = 30 - 2(w)
= 30 - 4
= 26cm.
Internal Breadth of wooden cuboid = 25 - 2(w)
= 25 - 4
= 21cm.
Internal Height of wooden cuboid = 20 - 2(w)
= 20 - 4
= 16cm.
Now,
Internal volume of wood = 26 * 21 * 16
= 8736cm^3.
Therefore volume of the wood in the cuboid = 15000 - 8736
= 6264cm^3.
Hope this helps!
