V=
(x+4)(x+4)(x+4)
Step 1: Multiplying from left to right, you notice that you're squaring a binomial. So, you'll get a perfect square trinomial.
 Step 2: Rewrite the equation:

Step 3: Multiply each term in first parentheses by each term in the 2nd.
x
^{2}*x+x
^{2}*4+8x*x+8x*4+16*x+16*4
x
^{3} + 4x^{2} + 8x^{2} +
32x + 16x + 64
Step 4: Combine like terms:
V =
