Final answer:
The surface area of a cube with each face having an area of 7 cm^2 is 42 cm².
Step-by-step explanation:
The surface area of a cube can be found by multiplying the area of one face by 6, since a cube has 6 equal faces.
The area of each face is given as 7 cm², so the total area of the cube is 7 cm² * 6 = 42 cm².
Therefore, the surface area of the cube is 42 cm².
