F(x) = x - 1
h(x) = -x + 1
(f o h)(x) = f(h(x)) = f(-x + 1) = -x + 1 - 1 = -x
(f o h)(7) = -7

Answer:
C. 468mm^2
Step-by-step explanation:
Using the formula for finding the surface area of cuboids [ S = 2(lw + lh + wh) ]
we have found the answer 468mm^2.
(Sorry for taking so long for a short explanation!
l = length , w = width , h = height . Just do the calculation with the algebra I have set out for you)
