Answer:

C. 32x² + 160x² - 96x

Step-by-step explanation:

Surface area of rectangular prism is given as 2(wl + hl + hw), where:

w = width = 4x

l = (10x - 6)

h = 4x

Surface area = 2[(4x)(10x - 6) + (4x)(10x - 6) + (4x)(4x)]

= 2[40x² - 24x + 40x² - 24x + 16x²]

Combine like terms

= 2[40x² + 40x² + 16x² - 24x - 24x]

= 2[96x² - 48x]

= 2(96x²) - 2(48x)

= 192x² - 96x

192x² - 96x = 32x² + 160x² - 96x

The answer is C. 32x² + 160x² - 96x
