There are four square pillars in the dining hall, 5 meters high. The bottom is a square with a side length of 6 decimeters and decorated with square bricks with a side length of 2 decimeters How many bricks? What is the volume of each square column?

Square column volume = bottom area * height = 0.6 * 0.6 * 5 = 1.8
You need to know how many square bricks there are. First, you need to calculate the surface area of the square column (the surface area here does not include the bottom area, only the side area is OK)
Surface area to be pasted = 0.6 * 5 * 4 = 12 * 4 = 48
The area of square brick is 0.2 * 0.2 = 0.04
48 / 0.04 = 1200 pieces
