You don't remember the volume formula for a cube ?

Example:  A box [ cube ]  has  2 inch  length, width, and  height...

so it's Volume is   2 in * 2 in * 2 in = 8 in^3   

Now can you find your Volume ?

Example:  my 2 inch cube  has  6  faces, 

and each face has area of  2 in * 2 in = 4 in^2

so the  Surface Area is 6 * 4 = 24 in^2

Now you can find your Surface Area

Volume V = s^3 = 4^3 = 64 cm^3

total surface area A   = 6*s^2 = 6*4^2 = 96 cm^2
