We know that
[volume of larger figure]=[scale]³*[volume of smaller figure]
scale=∛(volume of larger figure/volume of smaller figure)
scale=∛(2744/729)-----> 1.56

[surface area of the larger figure]=scale²*[<span>surface area of the smaller figure]
</span>[surface area of the smaller figure]=[surface area of the larger figure]/scale²
[surface area of the smaller figure]=[392]/1.56²----> 162 mm²

the answer is
the surface area of the smaller figure is 162 mm²
