10 = 64k h a h = 5·06 to 3sf s a
4 = 0·15625h² 10 = k × 8² h² = 4 ÷ 0·15625 s = kh²
k = 0·15625 s a kh² k = 64 ÷ 10 s = 0·15625h²

Place the cells in order to provide a clear logical solution to the following problem:

s is directly proportional to the square of h and s = 10 when h = 8. What is the value of h when s = 4?
