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

A 12x12 tile is 1 sq foot, so you will need 198 tiles.
15 exactly !

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.
If that is 60" tiles it would take 16 total.
