Area of each tile = 30*30 = 900 mm2.
Area to be covered = 1000*1000 = 1,000,000 mm2
So, number of tiles required = 1,000,000/900 = 1111.11... tiles.
150 tiles
30 square meters = ~322.92 square feet.
30 square meters is 300,000 square cm
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
A 30 m by 30 m square. Each of the tiles is 20 cm by 20 cm [20 cm = 0.20 m]. So 30 m / 0.20 m = 150. So you need 150 x 150 = 22500 tiles
150 tiles
If the tiles are 40x40 cm, each square meter will require 2.5 x 2.5, or 6.25 tiles. For 30 square meters then, you would need approximately 30 * 6.25 tiles, or 187.5 tiles. Of course, if you're doing real flooring and not a simple math puzzle, then .5 tiles are pretty useless, and you'd need to account not just for the area of the room, but the length and width.
30 square meters = ~322.92 square feet.
30 square meters is 300,000 square cm
30
Area = 30*40 = 1200 square meters
The answer depends on the shape of the 30 square feet area. If it is in the form of a strip that is 5 inches wide and 72 feet long and you don't want mosaics with little offcuts, then you will require 144 tiles.
Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
A 30 m by 30 m square. Each of the tiles is 20 cm by 20 cm [20 cm = 0.20 m]. So 30 m / 0.20 m = 150. So you need 150 x 150 = 22500 tiles
Lets do length and width in terms of tiles. The length is 6m/0.2m/tile 30 tiles and the width is 5m/0.2m/tile 25 tiles. Then the area is l X w 30 tiles X 25 tiles 750 square tiles. Since each tile is square, 750 tiles.
Answer: 30 m² = 322.917 ft²
