To calculate the number of tiles needed, we first determine the area to be covered.

### Floor Area:
- Each side of the room is 1.5 meters, so the floor is a square with an area of:
\[
1.5 \, \text{m} \times 1.5 \, \text{m} = 2.25 \, \text{m}^2
\]

### Wall Area:
- Each wall is 1.5 meters wide and 3 meters high, so the area of one wall is:
\[
1.5 \, \text{m} \times 3 \, \text{m} = 4.5 \, \text{m}^2
\]
- There are 4 walls, so the total wall area is:
\[
4 \times 4.5 \, \text{m}^2 = 18 \, \text{m}^2
\]

### Total Area:
- Total area to be tiled (floor + walls):
\[
2.25 \, \text{m}^2 + 18 \, \text{m}^2 = 20.25 \, \text{m}^2
\]

### Tile Area:
- Each tile is 30 cm x 30 cm, which is 0.3 m x 0.3 m, so the area of one tile is:
\[
0.3 \, \text{m} \times 0.3 \, \text{m} = 0.09 \, \text{m}^2
\]

### Number of Tiles Needed:
- Number of tiles required:
\[
\frac{20.25 \, \text{m}^2}{0.09 \, \text{m}^2/\text{tile}} = 225 \, \text{tiles}
\]

So, you'll need 225 tiles. That's a lot of tiles—enough to make your room feel like a giant game of Tetris!
