I think you're probably being asked to factor these expressions fully, but really, there are an infinite number of possible expressions for the dimensions. For example:

(3x2 - 12x), (1/x), and (x) are possible dimensions of the first cuboid

(3x2 - 12x), (x4-19), and (1/(x4-19)) are possible dimensions as well

But let's ignore that and just fully factor each expression for volume.

1.

3x2 - 12x

3(x2 - 4x)

3x(x - 4)

There are only three factors, so there is only one combination of possible dimensions:

3, x, and (x - 4)

Answer 2

Answer:

first we factorize

3x²-12x

3(x²-4x)

3x(x-3)

hence volume3x(x-3)
