800X800 ceramic tile is 50 yuan each, with an area of 70 square meters
Each box of 800 * 800 tiles has 3 pieces
The area of each box is 800 * 800 * 3 = 1.92 square meters
70 square boxes = 70 / 1.92 = 36.45 boxes (about 38 boxes including loss)
Total price: 38 cases * 3 pieces * 50 yuan / piece = 5700 yuan
But to be honest, the price is not so expensive. We know the price of 800 bricks
