Answer:

D. The volume is the product of the area of the base, (2x - 1)(x - 3), and the height x + 4.

Step-by-step explanation:

Volume of a Rectangular Block: V = lwh

Since we are given variables <em>l</em>, <em>w</em>, and<em> h</em>, we simply plug them in:

V = (2x - 1)(x -3)(x + 4)

We can see that we would need to multiply all 3 to find our volume. Therefore, our answer is D.

***Notice that the -3y^3 and 3y^3 just cancel out so all you have to do is the
