Area around
we see that all side are 4 legnth
therfor we have a cube
cube has 6 sides tha are sqyares

area of squaer=side^2
side=4

so
SA=6s^2
SA=6(4)^2
SA=6(16)
SA=96 cm^2

what you did is you found the volume

What you did is volume!
Surface area:
Take the area of one face on a cube. 4*4=16
Now multiply it by 6 because all 6 faces on a cube are equal in area.
You get 96 cm squared
