Answer 1

`V=168 \ in^3`

Explanation:

-The box material is 0.5 inches thick.

-The inside dimensions are therefore an inch thick less each.

-The volume of the inside is then calculated as;

`V=lwh\\\\=(8-0.5* 2)* (9-0.5* 2)* (4-0.5* 2)\\\\=7* 8* 3\\\\=168 \ in^3`

Hence, the inside volume is
`168 \ in^3`
