4 x 4, 5 x 5, ect all the way to 100 x 100.
400. That's because there are four six-by-six tiles in each square foot. 4 tiles per square foot X 100 square feet = 400 tiles.
100 tiles or 96 which is the correct amount
The perimeter of a square is 100 inches. How many square tiles 1 inch on each edge are needed to cover its area?
180
113 tiles

One side of a square is 10 inches long. How many one square inch tiles are needed to cover its area?
100
Each tile will cover 100 square inches. 12,000 square feet is 1,728,000 square inches. You will need 17,280 tiles.
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.
Five tiles will cover 160 square feet so they will cover 100% of 156 square feet with a little excess. A precise coverage will require 4.875 tiles.
Multiply the two dimensions to get the area. The calculation will give you 4 square feet for each tile and 100 square feet for 25 tiles.
