Three boxes are stacked one on top of the other. One box is 2 feet 8 inches tall, one is 4 feet 7 inches tall, and one is 3 feet 11 inches tall. How high is the stack?

Write your answer in feet and inches. Use a number less than
12 for inches.

Please explain

9 feet 26 inches

now I'm trying to figure out the next step. I know 12 inches 1 foot

26 / 12 = 2 feet, 2 inches

9 ft, 26 inches = 11 feet, 2 inches

To find the total height of the stack, you need to add up the heights of all three boxes. The first box is 2 feet 8 inches tall, so its height can be represented as 2 ft + 8 in. The second box is 4 feet 7 inches tall, so its height can be represented as 4 ft + 7 in. The third box is 3 feet 11 inches tall, so its height can be represented as 3 ft + 11 in.

To add the heights together, start with the feet. Add 2 ft + 4 ft + 3 ft, which equals 9 ft. Then, add the inches. Add 8 in + 7 in + 11 in, which equals 26 in.

Now, convert inches to feet if needed. Since we need to use a number less than 12 for inches, and 26 is greater than 12, we can simplify by dividing 26 in by 12. This gives us 2 ft remainder 2 in.

Finally, add the remaining feet and inches to the total height in feet. The total height is 9 ft + 2 ft + 2 in. So, the stack is 11 ft 2 in tall.

And your answer is?
