I don't think it takes the cube of it. There are 56 bits in one key, and 112 bits in two keys, so there could not be an entropy of more than 112 bits to triple DES. It is no more cryptographically secure than double DES because it uses 2 keys.
Wouldn't "triple-DES" imply three keys, or did I miss something?
