Answer:
27 cubic millimeters
Step-by-step explanation:
Remember that a cube's surface area is [tex]SA=6s^2[/tex] where [tex]s[/tex] is any side length of the cube.
Hence, by solving [tex]54=6s^2[/tex], we find that the side length of a cube is 3 millimeters.
This means that the volume of the cube is [tex]V=s^3=3^3=27mm^3[/tex]
