Hello,
<span>SA = s^2 + 2 × s × l
Base = 4
SA= 4^2 + 2 x 4 x l
SA= 16 + 2 x 4 x l
SA= 16 + 8 x l
Simplified, the surface area of a square pyramid with a base of 4 and an </span>unknown length/height (l) is SA= 16 + 8 x l.

75% I think.
because if you do 560 - 420 you get 140.
140 / 560 x 100 = 25
which means there is a 25% decrease, so they took 75%.
