What language are you programming in? Whatever print function you have it should probably go something like this. The volume = 343 The surface area = 294
To calculate this in code you could just use print(343-294);
Or you can use this (You can swap out the 7s for the variable length)
125% because sixteen is equal to a whole which is equal to one-hundered and one fourth of sixteen is four and sixteen plus four is twenty. one fourth of one-hundered is twenty-five so you add the twenty-five to the one-hundered and you get 125%
