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

v = 7b^4-28

Where 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)").

One solution could be:

b=5 and V =7*5^4 - 28 =4,347 m^3

4,347 =23 x 21 x 9
