Answer:
165 cm³
Step-by-step explanation:
Since the wood is 0.5cm thick and this is on all four sides, as well as top and bottom, the box measures internally just 2×0.5cm = 1cm less in each dimension.
That is, internally it measures 9 cm long, 7 cm broad and 5 cm high.
Now
volume of wood used
= volume of whole box (externally) - volume of inside of box
= 10 × 8 × 6 cm³ - 9 × 7 × 5 cm³
= 480 cm³ - 315 cm³
= 165 cm³
