Questions & Answers

Q: How can we calculate the height of each story in a building?

To calculate the height of each story, divide the total height of the building by the number of stories. In this case, it is 63 feet divided by seven stories, which equals nine feet per story.

Q: What information is needed to solve the problem?

The only necessary information is the total height of the building and the number of stories. Other details, such as the address and number of windows, are not relevant.

Q: How do you determine the height of each story by skip counting?

By skip counting by sevens (the number of stories), you can find that seven times nine equals 63. This means that each story is nine feet tall, as the total height of 63 feet is divided equally among the seven stories.

Q: Can we verify that the height of each story follows the pattern?

Yes, by adding nine feet for each additional story, starting at nine for the first story, you can see that the top of the seventh story (and the building) will indeed be 63 feet, confirming the pattern.

Summary & Key Takeaways

• The video discusses a problem about finding the height of each story in a building with a total height of 63 feet and seven stories.

• The problem requires dividing the total height by the number of stories to determine the height of each story.

• By skip counting by sevens, it is determined that each story in the building is nine feet tall.
