Answer:
38cm taller
Step-by-step explanation:
jack is 178cm tall
the ladder is 280cm tall
jack standing on the ladder is 280cm taller
so 178+280=458
the tree is 420cm tall
458>420
which means that jack is now taller than the tree standing in the ladder
458-420=38
so jack is 38cm taller than the tree standing on the top of the ladder
