A swimming pool is 50 meters long, 25 meters wide and 2.5 meters deep. How many square meters of ceramic tiles should I buy at least for the surrounding and bottom of the pool

A swimming pool is 50 meters long, 25 meters wide and 2.5 meters deep. How many square meters of ceramic tiles should I buy at least for the surrounding and bottom of the pool

Surface area = 50 * 25 + 50 * 2.5 * 2 + 25 * 2.5 * 2
=1 625 square meters of ceramic tiles
Answers to practical questions
Like this question oneself tries under, next time will be able to!

A swimming pool with a length of 50 meters, a width of 25 meters and a depth of 2 meters is pasted with ceramic tiles around and at the bottom. How many square meters is the area covered with ceramic tiles? If it is full of water, how many cubic meters is its maximum volume?

Area: (50 + 25) × 2 × 2 + 50 × 25 = 1550 square meters
Volume: 50 × 25 × 2 = 2500 m3

A gymnasium is going to build a swimming pool, which is 100 meters long and 60 meters wide, with an average depth of 2 meters. How much earth does it need to dig? (1 square = 1 cubic meter)

Volume = length x width x height = 100 * 60 * 2 = 12000 (M3) = 12000 (M3)

The school is going to build a swimming pool with a length of 100 meters and a width of 60 meters. It is estimated that the average depth of the swimming pool is 2 meters, which needs to be excavated in many ways. There is another problem to be solved
If you put tiles on the bottom and around the swimming pool, how many square meters is the area of tiles?

Tile: 100x60 = 6000 (M2)
100x2x2 = 400 (M2)
60x2x2 = 240 (M2)
6000 + 400 + 240 = 6640 (M2)
Excavation: 100x60x2 = 12000 (M3)
It should be right, ha ha
