How many square feet are in 28'x16'floor?
448
What is the Square Footage of an 8 Foot Circle?
Area of a circle = pi x r squared (Circumference = 2 x Pi x r) So that's 3.142 x 4 x 4 feet 3.142 x16 =50.272 sq feet
How many 16''x16'' floor tile pieces does it take to cover 560 sq ft?
Roughly, 315 tiles. First, you must convert the size of your tiles (inches) to the same measurement used to describe the room size (square feet). To figure the number of square feet per tile: 16" x 16" = 256 square inches per tile. Next, consider that there are 144 square inches in one square foot (12 in x 12 in). Now calculate: 256 (square inches per tile) divided by 144 (square inches in a square foot) = 1.78 sq in per tile. Now your units of measurement are the same - square feet. So you can now calculate how many tiles are needed for the space: 560 sq feet divided by 1.78 sq feet per tile = 314.6 tiles. Remember to add 5-7% extra for waste, because you'll cut the tiles to fit around edges and won't use every little scrap. Realistically, you'll need 330-337 tiles total for the project.
