Answer:
[tex]\huge\boxed{\text{The answer for part b) is 96}}[/tex]
Step-by-step explanation:
Right away, because the scale factor of the dilation is 1/2, which is less than 1, the new surface area should be less than the original. Simply multiply each side length by 1/2, then recalculate for surface area to get 4*4*6, or 96.
Hope it helps :) and let me know if you want me to elaborate.
