Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.

Multiply 2x^2 by 4 (A times C)

Find what numbers multiply to give you 8 and add to give you 7.

When you do this, you will notice that there are no numbers that do this. That makes your answer D. NONE OF THESE.

The correct option is Option 4: $2a^2b^3 + 10ab^4$

Step-by-step explanation:

Given

Length of box = l = ab

Width of box = w = a+5b

Height of box = h = 2b^2

The volume of a box is given by:

$V = Length*Width*Height\\V = l*w*h$

Putting the values

$V = (ab)(a+5b)(2b^2)\\ = (ab)(2b^2)(a+5b)\\=(2ab^3)(a+5b)\\Distributive property\\=(2ab^3*a) + (2ab^3*5b)\\=2a^2b^3 + 10ab^4$

Hence,

The correct option is Option 4: $2a^2b^3 + 10ab^4$
