A swimming pool is 50 meters long, 25 meters wide and 2 meters deep. When it is built, it is necessary to paste ceramic tiles on its four walls and bottom. At least, how many square meters of ceramic tiles should be pasted?
(50×25+50×2+25×2)×2=2800
A new rectangular swimming pool will be built in the gymnasium, 50 meters long, 21 meters wide and 2.4 meters deep. Now, tiles will be pasted on the four walls and the bottom of the pool, and a square with a side length of 0.2 meters will be used
Tiles, at least how much
(2.4x21x2 + 50x2.4x2 + 50x21) △ 0.04 = 34770 (pieces) a: at least 34770 pieces are required
Gymnasium to build a cuboid swimming pool, 40 meters long, 25 meters wide, 2 meters deep, pool around and the ground with tiles
If you use 25 tiles per square meter, how many tiles does the pool need? How many liters of water can it hold?
1. First ask for the surface area of the swimming pool, and then multiply by the number of tiles per square meter, OK!
40*25+（25*2+40*2）*2
=100+260
=360 square meters
360 * 25 = 9000 yuan
2. The maximum capacity of a swimming pool is to hold more than one liter of water
40*25*2
=2000 m3
2000m3 = 2000000l
