1. The formula for calculate the volume of the box is shown in the problem:

 V=lwh

 V is the volumen of the box.
 l is the length of the box.
 w is the widht of the box.

 2. When you substitute the values shown in the figure attached, into the formula V=lwh, you obtain:

 V=(2x-1)(x+2)(3x+1)

 3. You must apply the "Distributive property". Then, you have:

 V=6x³+11x²-3x-2

 Which expression represents the volume of the box? 

 The second expression, which is: 6x³+11x²-3x-2
