It depends on whether the tiles are 18 inch * 18 inch or 18 cm * 18 cm, etc. And also on whether the room is 10ft *10ft or 10 yards*10 yards or 10 metres*10 metres etc.

The answer will depend on whether the room is 10 inch by 10 inch (in a toy house, for example), or 10 ft x 10 ft or 10 yards x 10 yards. It is not possible to give a sensible answer without that information.

19 feet 1 inch by 21 feet 10 inches = 416.65 square feet.
First, find the square footage of a 6" x 36" plank. 6 x 36 = 216 square inches. There are 144 square inches in a square foot (12" x 12" = 144). So divide 216 by 144 to get the square feet per plank. 216 / 144 = 1.5 sq ft per plank. Your room is 16' x 12'. Multiply the two numbers to find square footage of the room: 16 x 12 = 192 square feet. You have 192 square feet, using planks that are 1.5 sq ft each. 192 / 1.5 = 128 planks. Generally, you will want to add from 5% to 10% for waste, depending on your layout (is it one big room, or several smaller rooms with lots of cutting?) (are you doing a straight layout, or diagonal?) and your skill level. If in doubt, add 10% to be safe. 128 planks + 10% --- that's 128 x 1.1 = 140.8 planks.
