Number of tiles required = roundup(area to be covered/area of each tile) where both are measures are expressed in the same units.
For the above calculation, you need to know the size of the tiles. You also need to know how "well-behaved" the area is. That will give an idea of how many tiles need to be cut. Then, depending on your skill level, you need to get 5-10% extra.
12 in = 1 ft, so each tile is 1 ft sq ⇒ you'll need 6 rows with 4 tiles in each row giving a total of 6 x 4 = 24 tiles.
you * it by the length of your floor
18x20 = 3603x4 = 12360/12 = 30 tiles for the floor :)
100 As 12 inch = 1 foot 10 x 10 = 100 100 / 1 = 100
You would need 56 tiles to do the floor
About 128.
Floor tiles do not kill cockroaches. You will need to use a pesticide.
The number of tiles needed to cover the floor is a function of the size of the tiles

The tiles do not have to be black, they just make it to be black.

You start by weep the vinyl tiles with a broom. Then Wash the vinyl tiles with disodium phosphate, using a nylon pad. What you need to do next uis rinse vertical-running tiles with wet rags. Rinse floor tiles with a mop. Let the vinyl tiles dry for two hours.
52 tiles (with a bit left over !)
I depends on what kind of flooring you are getting like 1x1 tiles or wood floor.
