8 cm.

Explanation: a cube has 6 faces, so divide 384 by 6 to find the area of one of the sides. you will get 64. get the square root of 64 to get one of the sides. which is 8

I think surface area is length times width times 6.

IF I'm right about that, it would be:

x^2 x 6= 384cm

divide 6 from both sides and get :

x^2= 64

then get the square root...

so x= 8

I hope that's right
