There are ten steps in front of the gate of Huangqiao Grand Theater. Each step is 6 meters long, 0.8 meters wide and 0.2 meters high. 1 how many square meters does the ten steps cover? If the steps are paved with floor tiles, at least how many square meters should they be paved? It's better to write down what you think and what you calculate in each step! If it's good, extra points!

Can't draw, sorry! Please imagine the cube model
1) To find the floor area is to find the floor area
The highest floor is 6 meters long, 0.8 meters wide and 0.2 meters high
The second floor is 6 meters long, 0.8 * 2 meters wide and 0.2 meters high due to a section protruding from the top floor
……
There are nine sections in front of the last layer, that is, the tenth layer, and one more section is highlighted
Therefore, it is 6 meters long, 0.8 * 10 meters wide and 0.2 meters high
To sum up, the ten steps cover a total area of 6 * 0.8 * 10 = 48 square meters
2) How many square meters do you need to lay at least
Move the horizontal plane of each step up horizontally and the vertical plane up vertically
The upper surface is 6m long, 0.8 * 10m wide and 0.2 * 10m high
Therefore, at least 6 * (0.8 * 10) + 6 * (0.2 * 10) = 60 square meters
Draw a picture and think about it carefully!
