very good

estimate

Today, after lunch, my father and I stood on the balcony and watched the scenery of the garden. Suddenly, my father asked me, "Can you estimate how many families there are in the north area of the seaside garden?" This question stumped me. I can't knock on the door and ask!

I thought for a while and finally had an idea. There are four high-rise buildings in the north area of our seaside garden, each with 30 floors and 4 households on each floor. The formula is: 30× 4 = 120 (floor), 120× 4 = 480 (household), assuming there are 3 people in each household, 480× 3 = 1440 (person),1440 ?. Dad asked, "How did you get this number?" I quickly explained my problem-solving ideas clearly, and my father laughed!
