A = ¹/₂bh
A = ¹/₂(4z² - 10)(8z)
A = ¹/₂[4z²(8z) - 10(8z)]
A = ¹/₂(32z³ - 80z)
A = ¹/₂(32z³) - ¹/₂(80z)
A = 16z³ - 40z

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: $2a^2b^3 + 10ab^4$
