We will take LCM of 4, 6 and 8 because if we join the cuboids of these dimensions and then every dimension of these cuboids will be formed by 4, 6 and 8 but since we have to make a cube and cube has all sides equal therefore sides should be multiple of 4, 6 and 8 all of them

The smallest multiple of 4, 6 and 8 is LCM of them i.e. 24 therefore side of the smallest such cube will be 24

The GMAT will never ask you about a "cuboid." This is simply not one of the geometric terms tested.

There is really no point in studying from non-GMAT-like sources!

Agree with Ceilidh. However, if the term "Cuboid" is replaced by "Rectangular solid" then the same question deserves to be considered for GMAT Practice.
