For example, the length of the bathroom is 15 and the width is 16, so how many squares are there and

The algorithm on the second floor is not right, and tiles are also the most taboo to calculate like this.

Now there are very few 30*45 floor tiles on the market, so the landlord should ask about the ones that are pasted on the wall.

In that case, it is very simple, and there are two types of tiles: horizontal and vertical.

If it is horizontally pasted, the length of the tile is required, and the height of the tile is 8 (the height is more than this height if the meter is counted, of course, and the waistline), so this wall needs 28 tiles. In the same way, the meter wall also needs 28 tiles.

If it is vertically pasted, the meter needs 5 brick lengths, and the height of 4 bricks (meters, plus the waist line is about the same meters) This wall needs 20 tiles, and meters still need 20 tiles.

Of course. The area of the doors and windows is to be removed.

Length 15 Width 16???

You mean the square of the ground???

If it's the square of the ground, it's a meter by a meter, right? It's squared.

If it's a square wall, because of the height and the perimeter of the wall, you can multiply two numbers by the square number.

30*45 is generally a wall brick, a square is a square, you divide one by one square is about equal to a brick, a square needs 18 bricks

What is 15 and 16, it should be rice and rice! If so, square it and ask for 20 tiles.

It should be meters long and meters wide, right? Such words (squared. Tile 30 * 45 (should be porcelain) one square is a piece, then the wall does not minus the doors and windows is 110 pieces. 18 pieces of ground are needed (note, don't use porcelain tiles for the ground, don't be fooled!) To use floor tiles )
