Answer:

384 cm^2

Step-by-step explanation:

A = 6a^2    (a = side length)

A = 6(8^2)

A = 6(64)

A = 384 cm^2

More explain stuff:

a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D
