Each 10' x 10' tile measures 100 square feet and 3300 square feet divided by 100 square feet gives the answer that 33 tiles are needed.

One side of a square is 10 inches long. How many one square inch tiles are needed to cover its area?

The area of the tile (10 cm x 10 cm) = 0.1 m x 0.1 m = 0.01 m², so it takes 100 tiles to make a square meter. There are 200 m² in 10 m by 20 m, so you need 20000 tiles (20 thousand)
75 tiles would do it (a 12*12 inch time = 1 square foot) but you need 10% over this for waste so you need to get 83 tiles.
