## Solved Examples on Feet to Inches

1. Convert 7 feet and 6 inches to inches.

Solution:

To convert feet to inches, we multiply the number of feet by 12. Here, we will first convert 7 feet to inches and then we will add 6 inches to the result.

7 feet $\time$ 12 inches = 84 inches.

84 inches + 6 inches = 90 inches.

Therefore, 7 feet and 6 inches is equal to 90 inches.

2. A rope is 15 feet long. How many inches long is the rope?

Solution:

To convert feet to inches, we multiply the number of feet by 12.

So, 15 feet $\times$ 12 = 180 inches.

Therefore, the rope is 180 inches long.

3. A person’s height is 5 feet 9 inches. How many inches tall is the person?

Solution:

To convert 5 feet to inches, we multiply 5 by 12.

5 feet $\times$ 12 inches = 60 inches.

5 feet 9 inches = 60 inches + 9 inches = 69 inches.

Therefore, the person is 69 inches tall.

4. Sara is 4 feet tall. Jeffrey is 42 inches tall. Who is taller?

Solution:

We cannot compare two heights with different units.

Let’s first convert 4 feet into inches.

To convert feet to inches, multiply the number of feet by 12.

4 feet $\times$ 12 = 48 inches.

Here, 42 inches < 48 inches

Sara’s height is greater than Jeffrey’s height.

Thus, Sara is taller than Jeffrey.

5. A wall is 120 feet tall. If a ladder can reach up to 20 feet, how many inches short is the ladder?

Solution:

Height of the wall = 120 feet.

Ladder reaches up to 20 feet.

Shortage in feet = 120 feet – 20 feet = 100 feet.

To convert feet to inches, multiply the number of feet by 12.

Thus, shortage in inches = 100 $\times$ 12

= 1200

Therefore, the ladder is 1200 inches short of reaching the top of the building.
