Answer:
54 cm²
Explanation:
Since it's a cube all sides must be equal. So, the length of one side is equal to the cube root of the volume.
∛27 = 3
An area of one surface is 3² = 9
Since the area of all the surfaces of the cube are equal, we can say that the surface area of the cube is 9 x 6, because there are 6 faces on a cube.
9 x 6 = 54
So, this means that the surface area of the cube is 54 cm².
