b) \( 375 \times 220 \) d) \( 140 \times 250 \times 500 \) i) \( 602 \times 100 \times 50 \)

Did you know that multiplying numbers with zeros can make calculations a lot easier? For example, in the case of \( 375 \times 220 \), you can break it down as \( (375 \times 22) \times 10 \) to simplify your math! This nifty trick can save you time and help avoid errors in your calculations. Another fun fact: the product of \( 140 \times 250 \times 500 \) can be visualized as finding the volume of a rectangular prism! Imagine a box where the length is 140, the width is 250, and the height is 500 — that big box holds a whopping \( 17,500,000 \) cubic units! This real-world connection can help make such large numbers feel more tangible.
