Let's break down the three problems from the image one by one.

### Problem 1: 
**Ladder Length and Empire State Building Height**

- **Given**: 
  - A ladder is 12 feet long.
  - The store has 295 ladders.
  - The Empire State Building is 1,453 feet tall.

- **Question**: 
  Would the ladders reach the top of the Empire State Building if placed end to end?

- **Solution**:
  To solve this, multiply the number of ladders by the length of one ladder:
  \[
  295 \times 12 = 3540 \text{ feet}
  \]
  The total length of the ladders would be 3,540 feet, which is greater than the height of the Empire State Building (1,453 feet).

- **Answer**: 
  Yes, the ladders would reach the top of the Empire State Building. In fact, they would exceed the height significantly.

### Problem 2:
**Library Book Donation**

- **Given**: 
  - The library received 42 boxes of books.
  - Each box contains between 15 and 18 books.
  - The library has 10 empty bookshelves.
  - Each bookshelf holds 60 books.

- **Question**: 
  Does the library have enough shelf space for all the new books?

- **Solution**:
  First, estimate the number of books donated. The number of books ranges from:
  \[
  \text{Minimum} = 42 \times 15 = 630 \text{ books}
  \]
  \[
  \text{Maximum} = 42 \times 18 = 756 \text{ books}
  \]
  Now, check the total shelf capacity:
  \[
  10 \times 60 = 600 \text{ books}
  \]
  The library can only hold 600 books on its shelves, which is less than the minimum estimate of 630 books. 

- **Answer**: 
  No, the library does not have enough shelf space for all the new books.

### Problem 3:
**Nishant's Box Tops Collection**

- **Given**: 
  - Nishant has 38 folders.
  - Each folder contains 80 box tops.
  - The number of box tops needed:
    - Printer: 1,500
    - Digital camera: 3,500
    - Tablet computer: 5,000

- **Question**: 
  Does Nishant have enough box tops for each of the three items?

- **Solution**:
  Calculate the total number of box tops Nishant has:
  \[
  38 \times 80 = 3040 \text{ box tops}
  \]

  Compare this with the required number of box tops for each item:
  - Printer: Needs 1,500 (Yes, Nishant has enough).
  - Digital Camera: Needs 3,500 (No, Nishant has less than this).
  - Tablet Computer: Needs 5,000 (No, Nishant has less than this).

- **Answer**: 
  - Nishant has enough box tops for the printer.
  - He does not have enough box tops for the digital camera or the tablet computer.

### Follow-up Questions:
1. How can you generalize the method of estimating when working with ranges, like in Problem 2?
2. What would happen if the number of books per box in Problem 2 was slightly less than 15?
3. How could Nishant collect the remaining box tops for the digital camera?
4. How would you apply similar reasoning to a real-world scenario where precision matters more?
5. What is the importance of estimation in simplifying real-life calculations?

### Tip:
When estimating with powers of 10, round numbers to the nearest power of 10 (e.g., 295 ladders becomes 300), which can make quick calculations easier without losing much accuracy.

Learn how to solve real-world math problems using estimation with powers of 10. This includes determining if ladders reach the Empire State Building, whether a library has enough shelf space for new books, and if enough box tops are collected for a printer, digital camera, or tablet.
