Final answer:
Ben's height is 4 ft 1 in.
Step-by-step explanation:
To find Ben's height, we need to follow the given information step by step.
1. Jamal is 5 inches taller than Ben.
2. Lacey is 2 inches taller than Jamal.
3. Zack is 4 ft 3 in tall and Lacey is 9 inches taller than Zack.
From the information, we know that Lacey is 2 inches taller than Jamal and 9 inches taller than Zack. So, Jamal's height is 2 inches less than Lacey and Lacey's height is 9 inches more than Zack. Therefore, Jamal's height is 9 - 2 = 7 inches more than Zack's. And since Jamal is 5 inches taller than Ben, we can conclude that Ben's height is 7 - 5 = 2 inches shorter than Zack's height. So, Ben's height is 4 ft 3 in - 2 in = 4 ft 1 in.
