The swimming pool is 50 meters long, 25 meters wide and 2 meters deep. How many tiles are needed to paste 4 square decimeters on its four walls and bottom?

Swimming pool surface area = bottom area + side area = length x width + 2x length x depth + 2x width x depth = 1550 square meters
1550 square meters = 155000 square decimeters
Swimming pool surface area divided by tile area = 38750

How is floor tile calculated

Toilet floor tile 3.8 level, wall tile 18 level. Kitchen floor tile 6.2 level, wall tile 26 level, if buy 5 yuan a tile, specification is 200 mm * 200 mm, need to buy how many pieces, how to calculate, had better have a formula. Thank you
Wrong. The specification is 600 * 600mm, not 200mm * 200mm

The calculation method can be: the total area of the tile (floor tile) to be pasted △ the area of a tile (floor tile) = the number of tiles (floor tiles). For example, if your tile size is 200 × 200, the area of this tile is 0.2 × 0.2 = 0.04 (M2); the number of tiles needed for 18 ㎡ wall tiles is 18 △ 0.04 = 450

(2) A computer classroom needs 400 pieces of 3-decimeter-long square bricks. How many pieces of 4-decimeter-long square bricks do you need?

3×3×400=4×4×x
X = 225

An office needs 400 square bricks when it is paved with 30cm square bricks. If it is paved with 50cm square bricks, it needs such square bricks
How much?

The area of a classroom is 87.04 square meters, with a side length of 0.45 meters of square tiles. How many tiles do you need?

87.04 ÷ (0.45 × 0.45), = 87.04 ÷ 0.2025, ≈ 430 (pieces), a: 430 pieces of this kind of ceramic tile are required

The area of a classroom is 48 square meters. How many bricks are needed to pave the classroom with 50 cm square tiles?

First of all, we need to convert the unit of 50cm
50cm=0.5m
Square area = side length * side length = floor tile area = 0.5m * 0.5m = 0.25m2
48㎡ /0.25㎡ =192
So it takes about 192 bricks!
But also to take into account the installation of floor tiles when the gap, and irregular places need to wear and tear!

The balcony is 60 decimeters long and 1 decimeter wide. Mother uses 2 decimeters high and 3 decimeters bottom tiles to pave the floor. How many pieces do you need
