A boy’s height is 3 1/2 feet. A giraffe’s height is three times that of the boy’s height. How many inches taller is the giraffe than the boy?
(1 foot = 12 inches)
boys' height = 3 1/2 ft = 42 inches
giraffe = 3(42) or 126 inches
difference = 126-42 = 84 inches

To find out how many inches taller the giraffe is than the boy, we need to calculate the height of the giraffe and the boy in inches first.
Given that the boy's height is 3 1/2 feet, we can convert this into inches using the conversion factor that 1 foot is equal to 12 inches.
So, the boy's height in inches = 3 1/2 feet * 12 inches/foot.
To simplify the calculation, let's convert 3 1/2 into a mixed number: 3 1/2 = 7/2
Now, the boy's height in inches = (7/2) * 12 = 84/2 = 42 inches.
Since the height of the giraffe is three times that of the boy's height, we can calculate the giraffe's height as follows:
Giraffe's height = 3 * Boy's height = 3 * 42 inches = 126 inches.
Finally, to find out how many inches taller the giraffe is than the boy, we subtract the boy's height from the giraffe's height:
Giraffe's height - Boy's height = 126 inches - 42 inches = 84 inches.
Therefore, the giraffe is 84 inches taller than the boy.
