Box 1. It is smaller than

If SA = 200
the sides are 2(5*5) + 4(5*y)
200 = 50 +20y
150 = 20y
y = 7.5

If SA is smaller then
>200 = 50 + 20y
>150 = 20y
Therefore 20y is less than 150
Therefore y is less
Therefore the volume is smaller

(a) Total SA = 50 + 20y = 200, so y = 7.5cm
Volume = 5*5*7.5 = 187.5(cm^3)
(b) It is smaller

You got the right answer but in completely the wrong way. (Just luck)
Part a makes you assume that SA is 200 and then (as you did) you can work out y and then the volume.
So you did part A correct

Part b then says that the SA is less than 200. What does this do to the volume in comparison to part A
You just measured whether the volume is greater than or less than the surface area
You were meant to see whether the volume is bigger or smaller when the surface area is smaller

These look like the 2020 (locked) exam paper. Are the questions publically availlable, if so could you provide a link?

The code at the bottom of the images clearly said June 2020.
