Total size of the box is 160in.

One side is 5 inches. One side is twice that of the other. We know that the volume of a cuboid is the product of the 3 sides.$$5 x \times2x =160$$. Solve to find x which ends up being $$x = 10\frac{ 2 }{ 3 }$$From this we know that one is 5 the other is x and the other is twice x.
