20 in X 20 in = 5/3 ft X 5/3 ft.
Didn't list the actual dimensions of the area to be covered, just the total, so let's split it up in the most convenient way...
400 ft2 = 20 ft X 20 ft
20 ft / (5/3 ft) = 12 tiles per side (row)
12 * 12 = 144 tiles

The best way to figure out how many 13x13 tile will be needed to cover 30 sf of floor is to calculate 13x13/144 give coverage per tile (1.1736), then take 30/1.736 = 25.56 tiles.
100 + 10-15% = 110 - 115 pcs
0.13x0.13=0.017 sqm/tile x14=0.23 sqm/box 121: 0.23= 526 packs
Each tile covers 81 square inches. You have 1,296 square inches to cover. It will take 16 tiles to cover that area.
440 6-inch square tiles.
