500 sq feet = 500*12*12 = 72000 sq inches
Each tile is 20*20 = 400 sq inches
So, number of tiles required = 72000/400 = 180
This assumes that either the shape is such that only whole tiles are required or that all offcuts are used.

A 72-inch diameter circle has an area of: 28.3 square feet.
Divide both sides by 12 to change to feet:- 8/12 times 16/12 = 8/9 square feet
The perimeter of a square is 100 inches. How many square tiles 1 inch on each edge are needed to cover its area?
Oh, dude, let me break it down for you. So, one board foot is equal to one square foot of lumber that's one inch thick. If you have 200 board feet, that's like having a stack of wood that's 200 square feet in area and one inch thick. So, the answer is 200 square feet. Easy peasy!
