square feet

18 inches multiplied (x) by 18 inches = How Many Square Feet?
16 inches multiplied (x) by 16 inches = How Many Square Feet?

18" x 18" = 2.25 square feet ~ Is this right?
16" x 16" = 1.75 square feet ~ Is this right?

Re: square feet

18 inches * 18 inches = 324 square inches
16 inches * 16 inches = 256 square inches

324 square inches / 144 = 2.25 square feet
256 square inches / 144 = 1.78 square feet

20 x 20 WHAT? Inches, centimeters, millimeters?

10.8 sq ft looks suspiciously like 1 m². If the tiles are 20 x 20 cm, then a 5 x 5 array or 25 tiles.

Ultimately, you have to include grout width and figure cutting patterns when the size does not yield an integer number of tiles.

8" = 2/3 of a foot, so each tile's area is 2/3 x 2/3 = 4/9 ft²
9 tiles will cover 4 sq ft.

436.295 ft² x 9 tiles/4 ft² = 982 tiles

This ignores two things:
*Grout between the tiles. Instead of using the tile dimension, use the tile-to-tile spacing including grout and repeat. This will give fewer tiles.
*You will have to cut tiles to fit at the edges and you will have some scrap that is too small to fit anything. Allow at least 10% more.
