Answer :

Answer:

Step-by-step explanation:

volume of a cube =  L x W  x H  

  in a real cube    L = W = H

     so this becomes     Volume = s^3     where 's' is side length

   

V = s^3         now DOUBLE the side length to 2s

V = (2s)^3 = 8 s^3    <===== this is EIGHT times the original volume
