Step-by-step explanation:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.
Very glad I could help you!1
First, you know that 3/4 = .75. Now we can distribute. multipy -10*.75. Then multiply .75*2/5. Add those two answers together to get your final answer.
Substitute the numbers in the equation:

Since L=5in, W=4in and H=8in:

Therefore, the volume is equal to 160 inches cubed.
