A box that is 20cm x 20cm (square base) and 80cm tall will have this volume.
Also, one that is 40cm x 40 cm x 20cm tall...
Just a couple of sizes..

40x40x20 would also work.
There are unlimited dimensions that fit the criteria if one chooses to use the set of rational numbers along with integers.

I would say each dimension would be one side of a cube.
L=W,W=H,H=L the answer being 3X (20( cubert 4))
