    First, the formula of a rectangular prism : \(\sf \text{ SA = 2(wl +hl + hw)}\) If you're increasing it by a scale factor of 2, just expand each side by 2 and reapply the formula :)

    i got it because if it is larger by a scale factor of 2. then all you have to do if double the total for the orginal prism
