The volume (in cubic meters), V, of a rectangular room is given by the expression:

**v = 7b^4-28**

Where b is a positive integer and each dimension is a positive integer too. What are three unique expressions that could represent the dimensions of the room?

**In the answer box, write these three expressions as a product that equals the volume (e.g. "(expression 1)(expression 2)(expression 3)").**
